The Grading Gauntlet: Navigating NGC to PCGS Crossovers and the Perils of Regrading Your Premium Medals

Sometimes the plastic holder is holding the coin back. Let’s discuss the risks and rewards of trying to upgrade this piece across grading services.

In the numismatic world, few concepts generate as much heated debate—or as many financial pitfalls—as Cross-Over Grading. As a professional crack-out artist who has spent decades breaking open slabs, inspecting coins under magnification, and navigating the treacherous waters of the grading services, I can tell you firsthand that the line between a genuine upgrade and a costly mistake is razor-thin. Whether you are dealing with classic United States Mint medals, commemorative issues, or rare error pieces, attempting to “cross over” a grade from one service to another—say, upgrading an NGC MS-65 to a PCGS MS-67—carries significant risks. Today, we are going deep into the mechanics of NGC to PCGS crossovers, regrading protocols, the physical dangers of the crack-out, and how to spot the telltale signs of an undergraded coin.

Understanding the Grading Divide: NGC vs. PCGS Philosophy

The Battle of the Slabs

To understand cross-over grading, you must first understand the fundamental philosophical differences between the two dominant grading services in North America: the Numismatic Guaranty Corporation (NGC) and the Professional Coin Graders (PCGS). While both operate under strict standards, their methodologies differ in how they evaluate eye appeal, strike quality, and toning.

In my experience grading, NGC tends to be slightly more forgiving of natural toning and hairlines, often assigning higher grades to coins that possess a pleasing, albeit softer, appearance. PCGS, conversely, is notoriously strict on strike overlap, particularly in the recessed areas of early American medals. If a coin has slight die wear or soft striking in the fields, PCGS might downgrade it, while NGC might preserve the original strike.

This divergence creates the perfect storm for cross-over grading. A collector might purchase a medal based on an NGC grade, only to find that PCGS assigns it a lower grade. The realization that their “premium” investment might be sitting on a lower tier can be frustrating. However, the solution isn’t always to submit for regrading immediately; it requires a careful evaluation of the coin’s actual state versus its slabbed presentation.

The Plastic Holder: Holding Your Coin Back Digitally

Slab Protection vs. Grade Inflation

We live in an era where the plastic holder—whether it’s a slab, an envelope, or a plastic flip—often acts as a shield rather than a transparent window. The holder protects the coin from environmental damage, yes, but it also obscures the natural wear, marks, and hairlines that define a true grade.

When a professional crack-out artist examines a coin, we are looking for the raw truth beneath the plastic. We look for the micro-scratches, the tiny discolorations, and the subtle die chips that tell the story of the coin’s lifespan. A common trap is assuming that a coin graded MS-68 by one service is inherently superior to one graded MS-67 by another, simply because the plastic holder claims it is. But if the MS-68 coin lacks the raw surface detail to support such a grade, it is an inflated grade.

Before considering a cross-over, I always advise collectors to request the raw specimen if possible. Comparing the raw coin directly to the slabbed version is the only way to truly assess whether the grade reflects reality or merely the plastic environment.

Regrading: The Double-Edged Sword

The Financial and Emotional Math

Submitting a previously graded coin for regrading is a serious decision. It involves paying substantial fees—often upwards of $150 to $200 per submission—and subjecting your coin to the scrutinizing eyes of yet another grader. The process also carries inherent risks, particularly regarding the physical condition of the coin after it has been opened and resealed.

In my view, regrading should only be attempted if the coin in hand is genuinely uncirculated or proof, and if the original grade was clearly inflated by a misunderstanding of the coin’s true state. If you have a circulated medal sitting in an NGC holder rated MS-64, it is unlikely that PCGS will upgrade it to MS-67. The economics rarely work out, and the physical risk to the coin during the crack-out process usually outweighs the potential grade improvement.

However, there is a niche scenario where regrading makes sense: when a coin was graded for a specific variety or mintmark that is misidentified. For instance, if a collector has a medal with an “S” mintmark struck at the San Francisco Mint, but it was graded as if it came from the Philadelphia Mint without a mintmark, regrading to correct the attribution might yield a higher overall grade. This requires absolute certainty in the coin’s identity before spending the money.

The Crack-Out: Risks and Realities

Breaking the Seal, Breaking the Coin’s Future

As a professional crack-out artist, I have seen firsthand how the simple act of breaking a slab seal can inadvertently damage a coin’s future value. The process of cracking out a coin is not just flipping it over; it requires precision, patience, and an intimate understanding of the coin’s structural vulnerabilities.

Medals, by their very nature, present unique challenges during a crack-out. Unlike thicker bimetallic coins, many medals are thin-walled, consist of softer metals like bronze or copper, or feature highly detailed dies that are easily susceptible to micro-abrasions. When a high-grade medal is broken out of its slab, the pressure of the seal being broken can cause microscopic edge trims to chip, or the soft metal can be stressed, leading to hairline cracks that weren’t there before.

Consider the 1904 St. Louis World’s Fair “Silver Award Medal”—a square design measuring 2.625 inches by 2.625 inches, made of bronze (H-30-50, PCGS #804837). This is a raw medal, meaning it hasn’t been encapsulated since its original striking. While it is incredibly attractive, the thin bronze walls make it exceptionally vulnerable during a crack-out. A careless break can result in a chipped rim or a split in the planchet, destroying years of potential numismatic value.

Therefore, whenever you consider regrading or cracking out a slab, you must weigh the potential grade improvement against the physical risk of damaging the coin. A coin that is graded MS-67 but suffers a rim chip during the crack-out process becomes a coin that is merely MS-66 with a defect, negating any financial benefit.

Identifying the Undergraded: Red Flags in the Field

Subtle Signs of an Unfair Grade

One of the most valuable skills a professional crack-out artist possesses is the ability to identify undergraded coins before they are submitted for regrading. An undergraded coin is one that has been assigned a grade significantly lower than its true state warrants. Spotting these discrepancies requires a keen eye for detail and a deep understanding of the coin’s anatomy.

Here are the critical red flags I look for when evaluating a coin’s grade:

• Uniform Wear Pattern: Genuine circulation wear is never perfectly uniform. It follows the path of least resistance, often leaving die polish on high points and heavily abrading the fields. A coin graded MS-67 that looks perfectly smooth and uniform across all raised devices is likely artificially preserved or heavily polished.
• Lack of Strike Overlap: On medals, particularly those with recessed designs like the reverse of the Henry Clay medal, strike overlap is crucial. If the recessed areas (like the commemorative tablet or the allegorical figures) lack the crisp, overlapping detail expected at a given grade, the coin may be undergraded.
• Missing Mint Marks or Die Details: Sometimes, undergrading occurs because a mint mark was smoothed out, or a die crack was filled with polishing compound. A genuine MS-67 should exhibit all original die details, including subtle die cracks that have been worn down but still visible under magnification.
• Artificial Toning: While toning can be natural, a coin that appears uniformly toned across its entire surface, including the fields where no wear should occur, is suspect. This is common in older commemorative medals where improper storage has led to chemical toning.

Historical Context: Why Medals Matter in the Grading Game

The Henry Clay Medal and the Lincoln Connection

To fully appreciate the importance of accurate grading, we must look at the historical significance of the items we are grading. Take, for example, the massive U.S. Mint Medal of “Pure California Gold,” struck for presentation to Henry Clay in 1852. Abraham Lincoln, himself a admirer of Clay, once said of him: “Our country is prosperous and powerful; but could it have been quite all it has been, and is, and is to be, without Henry Clay? Such a man the times have demanded, and such, in the providence of God was given us.”

This 3.5-inch diameter, half-inch thick medal, containing nearly 30 ounces of gold, is a masterpiece of American medallic art. The dies were engraved by Charles Cushing Wright, the premier engraver of his time. The historical weight of this item cannot be overstated. A high-grade version of this medal commands a staggering premium in the market, as collectors are not just buying a gold coin; they are buying a piece of American history that shaped a nation.

If a dealer submits a circulated copy of this medal to PCGS and receives an MS-64, they are missing the mark entirely. The historical narrative is compromised by the poor grade. Conversely, if a collector has a genuine, well-struck uncirculated example and wants to cross over from NGC to PCGS, they must ensure the coin truly merits an upgrade. The strike must be flawless, the luster pristine, and the surface untouched.

The Stone Mountain Medal and Historical Accuracy

Another fascinating medal discussed in our forum community is the Stone Mountain medal. As collectors know, the Stone Mountain monument in Georgia features a massive Confederate memorial. However, as one astute member pointed out, the reverse of certain Stone Mountain medals depicts an inaccurate Confederate battle flag—one that is rectangular rather than the actual square battle flag of the Confederacy. I doubt the Confederate battle flag would be depicted at all today, given modern sensitivities.

When evaluating the grade of such a historically sensitive or historically inaccurate medal, I must consider the impact of the error on the grading process. Does the inaccuracy affect the technical grade? No, but it does affect the collectible value. An undergraded Stone Mountain medal might still be graded MS-65, but its market value might be depressed due to the historical controversy. Therefore, understanding the historical context of a medal is just as important as knowing its numerical grade.

Actionable Takeaways for Collectors and Dealers

1. Always Examine the Raw Specimen: Before spending hundreds of dollars on regrading, compare the raw coin to the slabbed version. If the raw coin lacks the detail to support the slabbed grade, the upgrade is illusory.
2. Respect the Thin Walls: Many medals, particularly those made of bronze or thin gold, are fragile. When cracking out a high-grade slab, use the utmost care to avoid chipping the rim or causing micro-fractures. The physical integrity of the coin is paramount.
3. Verify the Attribution First: Do not regrade a coin to fix a mintmark or attribution error unless you are absolutely certain of the coin’s origin. Misidentifying a coin as Philadelphia when it is actually San Francisco (or vice versa) will not yield a grade upgrade; it will only yield a misattribution.
4. Look for Strike Overlap on Recessed Areas: When evaluating medals with deeply recessed designs (like the tablet on the 1904 St. Louis World’s Fair medal), check if the recessed areas meet the fields sharply. Lack of overlap indicates a weaker strike and potentially an undergraded coin.
5. Consider the Market Value of the Grade: A coin graded MS-67 by either service is generally worth more than an MS-65, provided the grade is genuine. However, a coin that is artificially upgraded to MS-68 and then cracked out might reveal a coin that is merely MS-66 with surface defects, resulting in a net loss.

Conclusion: The Ultimate Goal of the Crack-Out

Navigating the treacherous waters of NGC to PCGS crossovers requires more than just a willingness to spend money; it requires a deep understanding of numismatic history, metallurgy, and the physical realities of the coins we handle. As a professional crack-out artist, my ultimate goal is never to “win” a grade battle, but to ensure that the coin in my hands accurately reflects its true state of preservation and historical significance.

The next time you encounter a “MEDAL MONDAY” submission or a premium graded medal that piques your interest, take a step back. Ask yourself: Is the plastic holder holding the coin back, or is the grade holding the coin back? By carefully examining the raw details, respecting the fragility of thin-walled medals, and understanding the historical context of the item, you can avoid the costly mistakes that turn a promising cross-over into a regrettable purchase.

True numismatic value lies not in the highest number on the slab, but in the authentic story told by the coin’s surface, its strike, and its place in the grand tapestry of history. Protect that story, and you will always come out on top.
