Planchet Flaws vs. Post-Mint Damage: A Field Guide to Authenticating 1922-D Lincoln Cent Variations

Is that a rare lamination flaw, or did someone gouge it with a screwdriver decades ago? That single question has cost collectors more money than almost any other mistake in the Lincoln cent hobby. Let me show you how to tell the difference.

The 1922-D Lincoln cent is one of the most fascinating — and most misunderstood — coins in all of American numismatics. It’s also one of the most treacherous. Between the famous Weak-D and No-D varieties, multiple die pairs, progressive die states, and a bewildering range of surface characteristics, this date demands a razor-sharp eye. After years of grading and attributing these pieces, I can tell you without hesitation: the single most common error collectors make is misidentifying post-mint damage as a genuine mint-produced variety — or worse, dismissing a legitimate rarity as damage.

In this guide, I’m going to walk you through the critical distinctions between planchet flaws, genuine mint-produced variations, and post-mint damage (PMD) on 1922-D Lincoln cents. We’ll cover lamination errors, clipped planchets, tooling marks, die cracks, die states, and the telltale signs that separate a $500 coin from a $5 one. Whether you’re eyeing a raw find from a roll or considering a six-figure RD premium example, this guide will give you the tools to make an informed call.

Why the 1922-D Lincoln Cent Is a Magnet for Misattribution

To understand why error attribution is so fraught on this date, you need to understand what was happening inside the Denver Mint in 1922. The facility was under enormous pressure to produce cents, and die preparation was rushed to the point of carelessness. The mintmark “D” was punched into the dies by hand, and in many cases, the punch was misaligned, struck too lightly, or partially obscured by aggressive die polishing. This created the famous “Weak D” and “No D” varieties that collectors obsess over to this day.

But here’s the problem — and it’s a big one. The very characteristics that make these varieties desirable — faint or missing mintmarks, uneven strikes, wavy or irregular surfaces — are also the hallmarks of post-mint damage. A coin that spent decades in a lucky piece holder can develop a wavy, distorted surface that mimics a legitimate die variety. A coin that’s been cleaned or scratched can lose detail that looks indistinguishable from a weak strike. And a coin with actual lamination peeling can be mistaken for a tool mark — or vice versa.

I’ve seen this play out firsthand. One forum member brought in a coin they believed showed the wavy reverse characteristic of Die Pair #3, only for renowned 1922 specialist Capt. Henway to identify it as lucky piece holder damage. The coin was still a new variety, but the waviness wasn’t a die characteristic — it was compression from decades inside a souvenir holder. That’s the kind of nuance that separates a knowledgeable collector from an overpaying one. And it’s exactly why understanding the difference between mint-origin flaws and post-mint damage matters so much for your pocketbook.

The 1922-D Die Pair System: A Quick Refresher

Before we get into damage attribution, let’s establish the framework. All 1922 Weak D or No D cents fall into one of seven recognized die pair categories, as documented by researchers including Sean Reynolds and Capt. Henway:

1. Die Pair #1 Weak D (Weak Reverse)
2. Die Pair #1 No D (Weak Reverse)
3. Die Pair #2 No D (Strong Reverse) — also called the 1922 Plain
4. Die Pair #3 Weak D (Weak Reverse)
5. Die Pair #3 No D (Weak Reverse)
6. Die Pair #4 Weak D (Weak Reverse)
7. Die Pair #4 No D (Weak Reverse)

Each die pair has specific markers — the position and strength of the D mintmark (or its absence), the strength of reverse lettering like “TRUST” versus “IN GOD WE,” the relationship of the L in LIBERTY to the rim, and the condition of the wheat stalks. Within each die pair, there are also die states — early, middle, and late — determined by the development of die cracks and wear patterns.

Here’s an example that trips people up constantly. Die Pair #3 specimens show three characteristic die cracks on the reverse: one at the 9 o’clock position, one at 11 o’clock, and one at 2 o’clock. But the earliest die state after cracks begin appearing may only show two of the three — the left wheat stalk crack develops later. Capt. Henway confirmed that roughly 15% of cracked pieces lack this third crack, and neither die state is considered rare. This is critical knowledge: if you see a two-crack coin, don’t assume it’s a different variety or that the third crack was worn away by circulation. It may simply be an earlier die state. That understanding alone could keep you from passing on a genuine variety or paying a premium for the wrong thing.

Lamination Errors: The Planchet Flaw That Mimics Damage

What Lamination Looks Like

Lamination occurs when a coin’s metal surface peels, splits, or flakes away from the planchet. It’s a planchet error, meaning it happened before the coin was struck — the metal itself was flawed, often due to impurities, trapped gas, or improper rolling at the strip mill. On 1922-D cents, lamination can appear as:

• A raised, blister-like area on the surface that may or may not have peeled
• A thin, flaking layer that’s partially detached, often on high points like Lincoln’s cheek or the wheat stalks
• A rough, granular patch that looks like corrosion but is actually exposed subsurface metal
• A split that runs parallel to the coin’s surface, sometimes visible on the edge

How to Distinguish Lamination from PMD

In my experience, lamination is most commonly confused with post-mint damage from cleaning, corrosion, or mechanical abrasion. Here’s how to tell them apart:

• Strike continuity: Lamination occurs before striking, so the design elements will flow uninterrupted across the laminating area. If the detail is missing or disrupted within the affected zone, it’s more likely PMD.
• Edge profile: Lamination often creates a visible lip or step at the boundary of the peeled area. PMD from scratching or tooling tends to have a V-shaped groove rather than a stepped edge.
• Surface texture: The exposed metal beneath a lamination peel often has a different texture — rougher, more granular — than the surrounding struck surface. PMD from chemical cleaning may show a uniform dullness or pitting.
• Location: Lamination can occur anywhere on the coin but is most common on high points and near the rim. PMD from tooling marks is often concentrated in areas where someone tried to “enhance” a mintmark or remove a blemish.

One important note: lamination errors on 1922-D cents are not particularly rare, given the rushed production conditions at the Denver Mint in 1922. A lamination flaw does not automatically increase value — in fact, it often decreases it — but it is a genuine mint error and should be attributed as such. Understanding its origin preserves the integrity of your attribution and helps you assess the coin’s true numismatic value.

Clipped Planchets: A Genuine Mint Error Often Overlooked

What Clipped Planchets Are

A clipped planchet occurs when the strip from which blanks are punched has an overlapping punch — the blank-cutting mechanism punches a blank from the edge of the strip, and the previous punch’s arc carries over, creating a curved clip. On 1922-D cents, clipped planchets are known to exist and are collectible, though they are not as famous as the mintmark varieties.

Identifying Clipped Planchets on 1922-D Cents

• Curved clip: A smooth, curved indentation on the edge of the coin, corresponding to the arc of the blanking punch. The metal flows inward at the clip boundary.
• Bowtie effect: On the opposite side of the clip, the metal often bulges slightly, creating a “bowtie” appearance where the two clip boundaries converge.
• Strike expansion: Design elements near the clip will appear stretched or incomplete, but the metal flow is natural — not sharp or angular.
• Burr lines: Genuine clips often show fine burr lines along the clip edge from the blanking process. These are raised, not incised.

Clipped planchets are frequently misidentified as damaged coins, especially by newer collectors who aren’t familiar with the blanking process. If you find a 1922-D with a curved clip, you have a genuine mint error — not PMD. These pieces carry their own collectibility and can add meaningful variety to a specialized Lincoln cent collection.

Post-Mint Damage (PMD): The Great Value Killer

The Many Faces of PMD

Post-mint damage is any alteration to a coin that occurs after it leaves the press. On 1922-D cents, I’ve seen every form of PMD imaginable, but the most common — and most deceptive — are:

• Tooling marks: Scratches or gouges made by a sharp instrument, often in an attempt to “improve” a weak mintmark or create the appearance of a No-D variety. Tooling marks are typically V-shaped in cross-section, have sharp edges, and cut through the coin’s patina.
• Lucky piece holder damage: Coins mounted in encased cents or “lucky piece” holders — popular souvenirs from the early 20th century — often develop wavy, distorted surfaces from the pressure of the holder. This can mimic die characteristics like the wavy reverse some collectors associate with Die Pair #3.
• Cleaning damage: Harsh cleaning — whether chemical, abrasive, or mechanical — removes the original surface of the coin, destroying luster and detail. On copper coins like the 1922-D cent, cleaning often leaves a telltale pinkish or unnaturally uniform color that no amount of retoning can fully disguise.
• Environmental damage: Corrosion from moisture, soil, or chemicals can create pitting, roughness, or discoloration that obscures genuine die features. This is especially problematic on copper cents, which are highly reactive and can deteriorate rapidly in poor storage conditions.
• Edge damage: Dents, rim bumps, and flattened edges from being dropped, stepped on, or run through a counting machine. Edge damage is the most common form of PMD and the least likely to be mistaken for a mint error — but it can still significantly impact eye appeal and value.

Tooling Marks: The Numismatist’s Nemesis

Tooling marks deserve special attention because they are the most intentionally deceptive form of PMD. On 1922-D cents, tooling is typically used to:

1. Create a fake No-D: Someone carefully scrapes or files away the weak D mintmark to make a Weak D coin appear to be a No D — a significantly more valuable variety.
2. “Enhance” a weak D: A faint D is deepened or sharpened to make the coin appear to be a different die pair or die state.
3. Remove encasement residue: Coins removed from lucky piece holders often have metal or paint residue around the rim, and collectors may try to clean this off, inadvertently creating tooling marks.

How to spot tooling marks:

• Directional scratches under magnification: Tooling marks have a consistent direction and often show multiple parallel lines from a multi-pointed tool.
• Disrupted patina: Genuine mint surfaces develop a natural patina over decades. Tooling marks break through this patina, revealing brighter, fresher metal underneath.
• Unnatural geometry: Mint-produced features — letters, numbers, design elements — have specific, consistent shapes. Tooling marks create irregular, angular disruptions that don’t follow the natural flow of the design.
• Metal displacement: Under high magnification, tooling marks often show tiny ridges of displaced metal along the edges of the scratch — evidence of material being pushed aside rather than simply abraded away.

Capt. Henway’s identification of lucky piece holder damage on a forum member’s coin — rather than a genuine wavy die variety — is a perfect example of the expertise required. The distortion was real, but its cause was post-mint, not a die characteristic. This distinction matters enormously for attribution, provenance, and ultimately, the coin’s market value.

Die Cracks and Die States: Mint-Produced Features That Mimic Damage

Understanding Die Cracks

Die cracks are raised lines on a coin that result from fractures in the die itself. As the die deteriorates from repeated striking, cracks develop and transfer to every subsequent coin struck. On 1922-D cents, die cracks are well-documented and serve as key markers for identifying die states within each die pair.

The three primary reverse die cracks on Die Pair #3 are located at:

1. 9 o’clock position on the reverse
2. 11 o’clock position on the reverse
3. 2 o’clock position on the reverse

Additionally, single die cracks are known on the reverse through the lower right wheat stalk and through the “O” in “OF.” These single-crack coins are less common than the three-crack variety but are well-established.

How Die Cracks Differ from PMD

Die cracks are raised features — the metal of the coin flows into the crack in the die, creating a thin, raised line on the coin’s surface. This is the opposite of a scratch or tooling mark, which is incised — it cuts into the surface. Under magnification, the difference is unmistakable:

• Die cracks: Raised, rounded profile; consistent width; follow a natural path that reflects the stress pattern in the die; show no disruption to the surrounding patina.
• Scratches/PMD: Incised, V-shaped profile; variable width; follow an arbitrary path; cut through the patina to reveal fresher metal.

As one forum member asked about a coin showing what appeared to be a die crack only on the lower right wheat stalk — a location they hadn’t seen before — the answer confirmed it was a known single die crack. This is the kind of knowledge that prevents you from dismissing a genuine die state as damage. Every time you correctly identify a die crack versus a scratch, you’re protecting the integrity of your collection and the accuracy of your attribution.

The Encasement Question: Can a Genuine 1922 No D Still Be in a Lucky Piece Holder?

This is a fascinating question that came up in the forum thread, and it deserves a thorough answer. Capt. Henway — who has done more research on 1922-D varieties than perhaps anyone alive — posed the question directly: if any legitimate 1922 No D cents had ended up in encasements back in the day, would they have been popped out by now?

The consensus answer, and I agree, is yes. The 1922 No D is one of the most famous and valuable Lincoln cent varieties. Any coin in an encasement would have been examined, and if it showed the diagnostic features of a No D variety, it would almost certainly have been removed and sold as a variety coin rather than remaining in its holder. The encasement premium for a lucky piece holder is a few dollars at most — the No D premium is hundreds or thousands.

This doesn’t mean you should ignore encased cents entirely, but it does mean that if you encounter one, the odds of it being a genuine No D are vanishingly small. The same logic applies to any high-value variety: the market incentive to remove and certify the coin far exceeds the value of keeping it in the holder. From a provenance standpoint, an encased coin should be approached with healthy skepticism — especially if the seller is marketing it as a rare variety.

Actionable Takeaways for Buyers and Sellers

Whether you’re buying, selling, or simply attributing your own 1922-D cents, here are the critical steps I recommend:

For Buyers

1. Always examine the coin under magnification — at minimum 10x, preferably 15x or 20x. Die cracks, tooling marks, and lamination all reveal their true nature under magnification. This single habit will save you more money than any other piece of advice I can offer.
2. Compare to known die pair markers. Use resources like LincolnCentResource.com to match your coin’s specific features — mintmark position, reverse letter strength, die crack locations — to established die pairs and states. Don’t rely on memory alone; even experienced attributors keep references at hand.
3. Trust certified coins when possible. A PCGS or NGC certification doesn’t guarantee perfection, but it provides a layer of expert attribution that’s invaluable for a date this complex. Note the forum statistics: only 12 out of 154 MS65RD/65+RD coins across both services have CAC stickers, so a CAC-approved coin at this grade is genuinely scarce and commands a premium accordingly.
4. Be skeptical of “No D” coins with tooling marks near the mintmark. If the area around the D shows unnatural scratches, filing, or disruption, walk away. No amount of wishful thinking turns a tooled coin into a genuine rare variety.
5. Consider the coin’s entire surface. A genuine die variety will have consistent characteristics across the entire coin — not just in one isolated area. Evaluate the luster, strike quality, and patina holistically before making a judgment.

For Sellers

1. Get a TrueView or equivalent high-resolution imaging. As one forum member noted after cracking a coin out of an undergraded holder, having professional photography (like PCGS TrueView) can make the difference between a coin selling at its true value and being overlooked. Strong images communicate eye appeal and build buyer confidence.
2. Submit to CAC if your coin is high-end. With only 2 CAC-stickered coins at MS66RB across both grading services, the CAC premium is real and significant. For premium examples, that green sticker can mean thousands of dollars in added value.
3. Attribute the die pair and die state accurately. A Die Pair #3 with two die cracks (early state) is a different market proposition than one with three die cracks (later state). Collectors pay attention to these details, and accurate attribution strengthens your provenance and your asking price.
4. Disclose any PMD honestly. A coin with lucky piece holder damage, cleaning, or tooling marks should be described accurately. The market for damaged coins is thin, and misrepresentation will cost you reputation and potentially legal liability. Honesty is always the best policy — especially in a community as small and well-connected as this one.

The Market Reality: Rarity, Grade, and the CAC Factor

The forum thread included some eye-opening population data that every 1922-D collector should internalize:

• MS65RD and MS65+RD combined: Only 154 graded across PCGS and NGC. Of those, only 12 have CAC stickers of any version.
• MS66RB: Only 7 graded (5 by PCGS, 2 by NGC), with only 2 meriting a CAC sticker.
• Die Pair #4 No D: Capt. Henway himself has not been able to confirm a high-grade example, suggesting it may be extraordinarily rare or possibly non-existent in the condition needed for definitive attribution.

These numbers tell a clear story: high-grade 1922-D cents in mint condition are genuinely scarce, and CAC-approved examples at the premium grades are exceptional. If you’re hunting for a top-pop or near-top-pop example, be prepared for a long search and a significant financial commitment. The collectibility of these pieces only increases as the supply of certified premium examples remains static.

At the same time, the die variety market is still developing. Capt. Henway’s forthcoming book promises to introduce several new varieties that are not yet in the standard references. This means that coins currently attributed to known die pairs may be reclassified — potentially increasing their numismatic value. It also means that the attribution landscape is more complex than any single reference can capture, making expert consultation all the more important.

A Word on the Expert Community

One of the most valuable takeaways from the forum discussion is the importance of expert attribution. Capt. Henway’s contributions to the thread — identifying lucky piece holder damage, confirming die states, noting new varieties, and providing population context — demonstrate the kind of deep expertise that no book or website can fully replace.

I encourage every 1922-D collector to:

• Engage with the specialist community on forums like this one
• Seek out the forthcoming book from Capt. Henway (publisher willing!)
• Reference established resources like LincolnCentResource.com
• When in doubt, submit your coin to a major grading service with a request for variety attribution

The difference between a correctly attributed coin and a misattributed one can be hundreds or thousands of dollars. Expert consultation is not a luxury — it’s a necessity. The more you invest in understanding the nuances of this date, the better your collecting decisions will be.

Conclusion: The Art and Science of 1922-D Attribution

The 1922-D Lincoln cent sits at the intersection of history, metallurgy, and human error — both at the mint and after the mint. Its varieties are the product of rushed die preparation, progressive die deterioration, and the quirks of early 20th-century minting technology. Its damage patterns are the product of a century of handling, mounting, cleaning, and — yes — deliberate alteration by those seeking to profit from the coin’s fame.

Sorting genuine mint features from post-mint damage is not always easy. Lamination can mimic corrosion. Die cracks can mimic scratches. Lucky piece holder distortion can mimic die characteristics. Tooling marks can mimic natural wear. But with careful examination, proper magnification, knowledge of die pair markers, and consultation with experts, you can make confident attributions that protect your collection and your investment.

The 1922-D Lincoln cent is more than a coin — it’s a historical artifact from a pivotal year in American minting, a numismatic puzzle with new pieces still being discovered, and a collectible whose market continues to mature as research advances. Whether you’re holding a raw VG weak D from a roll find or an MS65+RD with outstanding luster and eye appeal, you’re holding a piece of history that rewards careful study. The more you learn about its complexities, the more you’ll appreciate — and profit from — what makes this date one of the most compelling in all of American numismatics.
