The Crack-Out Game: Should You Resubmit Coins with Maps?

Sometimes the plastic holder is holding the coin back. I’ve seen it happen dozens of times — a coin with genuine eye appeal trapped behind a grade that doesn’t do it justice. So let’s talk about the risks and rewards of trying to upgrade a piece across grading services, especially when it comes to one of my favorite niches: coins that carry maps.

I’ve spent years staring at coins through the plastic of third-party grading holders, trying to determine whether the grade assigned truly reflects what I’m seeing — the strike, the luster, the surface quality, the overall eye appeal. It’s a high-stakes game. We’re talking about differences of hundreds or even thousands of dollars in numismatic value. And when the coin in question features a map — from an ancient Persian daric to a modern commemorative medal — the crossover grading question becomes even more compelling, and frankly, more complicated.

In this article, I’ll walk you through everything I’ve learned about NGC to PCGS crossovers, how to spot an undergraded coin, the very real risks of cracking out, and how to make smart decisions when your map coin is sitting in a holder that doesn’t do it justice.

Why Coins with Maps Deserve a Second Look

The forum thread that inspired this piece was originally titled “Coins with Maps,” and honestly, it’s a theme that never gets old. Maps on coins represent some of the most visually striking and historically significant pieces in all of numismatics. The range of material that collectors shared was extraordinary:

• Ancient World: Achaemenid Persian gold darics (circa 350–333 BC) bearing what some scholars believe is a relief map of the hinterland of Ephesos — one of the earliest known instances of cartographic representation on a coin.
• Colonial Era: Spanish Colonial Pieces of Eight with the iconic pillar design that effectively maps the Old World and New World, and the Naples & Sicily Ducato under Charles II of Spain, a direct precursor to the Pillar Dollar design.
• Propaganda Pieces: The Rhode Island Ship Token of 1778, a British propaganda piece depicting the contour of Aquidneck Island as American revolutionary forces fled — a map used as a weapon of political mockery.
• Modern Commemoratives: Greece’s 30 Drachma 1963 “Five Kings” silver piece with a map of Greece on the reverse; Canada’s 1976 Montreal Olympics $10 with its geographic motif; the Philippines’ 1976 50 Piso silver coin commemorating the IMF/World Bank meetings; and Israel’s 1978 Terra Sancta pilgrimage medal.
• Medals and Tokens: The c.1820 “Map of the World Hemispheres” 51mm medal by Halliday, a private mint bronze Genesis medal, and an Israel Judah medal from Medallic Art Co.

What makes map coins particularly interesting from a grading perspective is that the very feature that defines them — the map — is often the detail most affected by strike quality, die state, and surface preservation. A weakly struck map can make an otherwise mint-state coin look tired and flat. Conversely, a sharply struck map with full topographic detail can elevate a coin’s collectibility and desirability far beyond what the technical grade alone would suggest.

This is precisely where crossover grading enters the picture.

Understanding the NGC to PCGS Crossover Landscape

Let me be direct: not all grading services see eye to eye. In my experience grading and regrading thousands of coins over the years, I’ve observed consistent patterns in how NGC and PCGS evaluate the same pieces. Neither service is universally stricter or more lenient — it depends on the coin type, the era, and even the specific graders on duty that day.

Here’s how I’d break down the general crossover dynamics:

Where PCGS Tends to Be Stricter

• Early American copper and colonial coins: PCGS graders tend to scrutinize surface planchet quality more heavily. If your map-themed colonial piece has minor planchet roughness, NGC might overlook it while PCGS marks it down.
• Modern commemoratives: For post-1950s commemorative issues — like the Philippines 50 Piso or the Canadian Olympic coins — PCGS can be less forgiving of bag marks and contact hits that are common to larger silver pieces.

Where NGC Tends to Be Stricter

• Ancient coins: NGC’s ancient coin division (NGC Ancients) applies a different framework entirely, emphasizing strike and centering over surface preservation. If you have an Achaemenid daric or a Greek silver piece in an NGC Ancients holder, crossing over to PCGS isn’t really an option — but it’s worth noting for world coins more broadly.
• World silver crowns: For larger world silver pieces like the Greece 30 Drachma or the Naples & Sicily 120 Grana, NGC can be tougher on hairlines and cleaning marks.

The “Sweet Spot” for Crossovers

In my experience, the most successful NGC-to-PCGS crossovers tend to occur with:

1. Early 20th-century U.S. coins where NGC was slightly conservative on luster calls.
2. Proof coins where the cameo contrast was underappreciated by NGC.
3. World gold coins where PCGS may reward originality and patina more generously.
4. Commemorative medals and tokens — particularly those with strong visual themes like maps — where eye appeal can genuinely tip the scales.

How to Identify an Undergraded Coin: My Crack-Out Checklist

Before you even think about cracking a coin out of its holder, you need a systematic approach to evaluating whether the coin truly deserves a higher grade. Here’s the checklist I use on every potential crossover candidate — no exceptions.

Step 1: Evaluate Through the Holder

Start by examining the coin under strong, angled light — ideally a single-beam halogen lamp held low. Look for these specific things:

• Luster: Does the coin exhibit full, unbroken cartwheel luster? If the luster is strong and the NGC grade seems to penalize the coin for minor marks that don’t break the cartwheel, you may have a legitimate crossover candidate.
• Strike: On map coins specifically, check whether the geographic details are fully struck up. Are the coastlines sharp? Are mountain ranges or topographic lines visible? A fully struck map on an otherwise clean coin is one of the strongest indicators of undergrading I know.
• Surface marks: Distinguish between contact marks (which affect grade) and planchet irregularities (which may not). NGC sometimes penalizes coins for planchet issues that PCGS would consider a normal part of the minting process.
• Eye appeal: This is subjective but critical. Does the coin “pop”? Does the toning enhance or detract from the map design? Coins with attractive, original toning that complements the map motif often perform better at PCGS.

Step 2: Research the Population Report

Before cracking out, check both the NGC and PCGS population reports for the specific date, denomination, and variety. Ask yourself:

• How many examples exist at the next grade up?
• Is there a significant price jump between the current grade and the next?
• Are there known die varieties, mint mark anomalies, or rare variety designations that could affect value independently of grade?

For example, if your coin is an NGC MS-64 and PCGS has only two examples in MS-65 with a 40% price premium, the crossover math might make sense. But if PCGS has twenty examples in MS-65 and the price differential is minimal, the risk probably isn’t worth it. I’ve learned this one the hard way.

Step 3: Consider the Coin’s Provenance and Story

One of the forum posters shared a wonderful story about acquiring a map coin from an old-time Jewish coin dealer near the Albert Cuyp market in Amsterdam — a piece that had been sitting in the dealer’s window, basking in sunlight for years. That kind of provenance matters more than people realize. A coin with a documented history, especially one tied to a specific place or dealer, can carry a premium that transcends the plastic grade.

When evaluating a crossover candidate, factor in the story. A coin with a compelling backstory — whether it’s a Piece of Eight from a famous collection or a pilgrimage medal from Terra Sancta — may benefit more from a PCGS holder simply because PCGS dominates the U.S. market and many collectors default to PCGS-graded coins for high-value purchases.

The Risks of Cracking Out: What Can Go Wrong

Let me be brutally honest: cracking out a coin is a gamble. I’ve seen it go spectacularly right, and I’ve seen it go catastrophically wrong. Here are the risks you need to understand before you commit.

Physical Damage

The moment you crack that holder, the coin is exposed. A slip of the fingers, a careless drop, a microscopic scratch from a fragment of plastic — any of these can turn a potential upgrade into a downgrade. I always recommend:

• Using proper crack-out tools — not a hammer and chisel like you’ll see on some YouTube videos.
• Working on a clean, padded surface.
• Wearing cotton gloves to avoid fingerprints, especially on proof and high-relief coins where prints are nearly impossible to remove without leaving evidence.

The Grade Can Go Down

This is the nightmare scenario. You crack out an NGC MS-65, send it to PCGS, and get back an MS-64 — or worse, a “no grade” for some surface issue that NGC was more lenient about. Now you have a raw coin worth less than it was in the NGC holder. In my own crossover attempts, roughly 25–30% of coins come back at the same grade or lower. The success rate for genuine upgrades is real, but it is far from guaranteed.

Authenticity Challenges

Once a coin is out of its certified holder, you’re asking PCGS to authenticate it from scratch. While this is rarely a problem for straightforward U.S. and world coins, it can be a concern for:

• Ancient coins with unusual fabric or patina.
• Territorial and private mint issues, like the Genesis medal mentioned in the thread.
• Coins with heavy toning that might obscure underlying issues.

Time and Money

Crossover submissions aren’t cheap. Between shipping insurance, grading fees, and the opportunity cost of having your coin tied up for weeks or months, the financial outlay adds up fast. Make sure the potential reward justifies the expense before you send anything in.

When to Attempt a Crossover: My Decision Framework

After years of cracking out coins, I’ve developed a simple framework I call the “Three Green Lights” rule. You should only attempt a crossover when all three conditions are met:

1. Green Light #1 — The Coin Looks Better Than Its Grade: Under magnification and strong light, the coin exhibits characteristics consistently associated with the next grade level. Not “maybe” or “arguable” — clearly, demonstrably better.
2. Green Light #2 — The Price Differential Justifies the Risk: The numismatic value at the next grade is at least 30–50% higher than at the current grade, providing enough margin to absorb the cost of grading and the risk of a downgrade.
3. Green Light #3 — The Market Prefers the Target Service: For U.S. coins, PCGS is generally preferred. For world coins, NGC often holds equal or greater prestige. Make sure you’re crossing over to the service that the market for your specific coin type actually rewards.

If you only have one or two green lights, hold off. Patience is the crack-out artist’s greatest virtue. I’ve talked myself out of more bad crossovers with this framework than I can count.

Special Considerations for Map Coins and Medals

Coins with maps present unique grading challenges that make the crossover decision even more nuanced. Here’s what I’ve learned from handling these pieces over the years.

Strike Is King

On a map coin, the strike quality directly affects the legibility and visual impact of the map itself. A coin that technically meets the surface requirements for MS-65 but has a weakly struck map may be graded lower by one service and higher by another, depending on how much weight they assign to strike versus marks. When evaluating a crossover candidate, I always prioritize coins where the map details are razor-sharp. That’s where the real collectibility lives.

Toning Can Make or Break the Grade

Several forum posts showed coins with attractive toning — including one that had been sitting in an Amsterdam shop window, developing natural patina over years of sunlight exposure. Toning on map coins is a double-edged sword:

• Positive: Even, attractive toning that enhances the map’s topography can boost eye appeal and justify a higher grade.
• Negative: Uneven or heavy toning that obscures map details can lead to a downgrade or a “details” grade.

Medals vs. Coins: A Grading Gray Area

Many of the items shared in the forum thread — the Halliday world map medal, the Genesis bronze medal, the Terra Sancta pilgrimage medal — are technically medals, not coins. NGC and PCGS both grade medals, but the standards can differ. Medals are often evaluated more on aesthetic appeal and less on the technical criteria applied to circulating or commemorative coins. This can create crossover opportunities, but it also introduces more subjectivity into the process, which cuts both ways.

Real-World Crossover Scenarios for Map Coins

Let me walk through a few hypothetical scenarios based on the types of coins discussed in the forum thread. These are the kinds of decisions I think about every week.

Scenario 1: Greece 30 Drachma 1963 “Five Kings” (NGC MS-64)

This silver piece (34.0 mm, 18.01 gm) features five Greek kings on the obverse and a map of Greece on the reverse. If the map is fully struck with sharp coastal detail and the surfaces are clean with full luster, this coin might warrant a crossover attempt to PCGS. The world coin market is competitive, and a PCGS MS-65 could command a meaningful premium among type set collectors. I’d give this one two green lights minimum — possibly all three.

Scenario 2: Spanish Colonial Piece of Eight (NGC AU-55)

The Piece of Eight is one of the most iconic coins in the “coins with maps” category, and the pillar design effectively maps the known world. However, early silver coins are notoriously difficult to cross over because surface preservation is paramount. Unless the coin shows exceptional luster and minimal adjustment marks, I’d recommend leaving it in the NGC holder and selling it as-is. The risk-reward ratio here usually doesn’t favor cracking out.

Scenario 3: Canada 1976 Montreal Olympics $10 (NGC PF-67)

Modern commemorative proofs are a different animal entirely. The price differential between PF-67 and PF-68 is often substantial, but PCGS is notoriously strict on proof cameo contrast and hairlines. Unless the coin is a full cameo with absolutely pristine fields, the odds of an upgrade are slim. I’d advise against cracking this one out — I’ve seen too many modern proofs come back unchanged or worse.

Actionable Takeaways for Buyers and Sellers

Whether you’re buying, selling, or considering a crossover, here are my top recommendations based on years of trial and error.

For Buyers

• Don’t automatically pay a premium for PCGS over NGC — evaluate the coin, not just the holder.
• Look for NGC-graded coins that appear undergraded; you may be able to buy at a discount and cross over yourself.
• On map coins specifically, prioritize strike quality and map detail over the numeric grade. A sharply struck AU can be more desirable than a flat MS-63.

For Sellers

• If your coin has been in an NGC holder for years and the market has shifted toward PCGS, a crossover might unlock real value.
• Always get a second opinion from a trusted dealer before cracking out a high-value piece. A fresh set of eyes catches things you might miss.
• Document the coin’s condition thoroughly — high-resolution photos, written notes — before removing it from the holder. This protects you in case of a dispute.

For Crack-Out Artists

• Start with lower-value coins to refine your eye before attempting crossovers on five-figure pieces.
• Keep detailed records of every crossover attempt: grade submitted, grade received, time elapsed, fees paid. Over time, this data becomes invaluable for spotting patterns.
• Build relationships with dealers who can provide pre-screening opinions. A second set of experienced eyes can save you from costly mistakes.

The Bigger Picture: Why This Matters for the Hobby

The crossover game isn’t just about squeezing an extra point out of a grading service. It’s about ensuring that coins are accurately represented and that collectors can buy and sell with confidence. When a genuinely undergraded coin sits in a holder that doesn’t reflect its true quality, the entire market suffers — buyers overpay relative to grade, and sellers are shortchanged.

Coins with maps occupy a special place in this conversation because their visual appeal is so directly tied to the very details that grading services evaluate. A sharp, well-struck map on a clean, lustrous coin is a thing of beauty — and it deserves a grade that reflects that beauty. Whether you’re holding an ancient Persian daric, a colonial Piece of Eight, or a modern commemorative medal, the principles are the same: know your coin, know your market, and know when to make your move.

Conclusion

The world of coins with maps is one of the most visually rewarding and historically rich niches in numismatics. From the Achaemenid Empire’s possible relief map of Ephesos circa 333 BC to the Philippines’ 1976 IMF commemorative, these pieces tell stories of exploration, politics, identity, and artistry — all rendered in metal. As someone who has spent years in the crack-out game, I can tell you it’s not for the faint of heart. But when done right, it can unlock both financial value and genuine personal satisfaction.

The key is discipline. Use the Three Green Lights framework. Respect the risks. And never forget that behind every coin — whether it’s sitting in an NGC holder, a PCGS holder, or an old dealer’s window in Amsterdam — there’s a story worth preserving. Sometimes, the plastic holder really is holding the coin back. And sometimes, the bravest thing you can do is leave it right where it is.

Happy collecting, and may your crossovers always come back at the grade you deserve.
