How to Spot Rare Errors on My PCGS Submissions

Introduction: The Hidden Value in the Details

Most people overlook the tiny details that can transform a common coin into a rarity worth thousands. As an error coin hunter, I’ve learned that the difference between a $20 coin and a $2,000 coin often comes down to spotting the subtle variations that escape casual observation. When examining submissions like those I recently sent to PCGS, the devil truly is in the details.

Historical Significance of Die Variations

Every coin tells a story through its manufacturing process, and die variations are like fingerprints that reveal the coin’s journey from planchet to pocket. The Morgan dollar I recently crossed from NGC to PCGS was originally purchased back in 2021-22, before I became serious about grading. What makes certain die variations valuable isn’t just their rarity, but the historical context they provide about minting practices of their era.

Die cracks, for instance, form when the immense pressure of coin striking causes metal fatigue in the die itself. These cracks appear as raised lines on the coin’s surface and can range from barely visible to dramatic raised features. The 1888-O “Hot Lips” Morgan dollar, where a die crack created what appears to be the Liberty figure with exaggerated lips, can command premiums of 10-20 times a normal specimen.

Double Die Varieties: The Collector’s Holy Grail

Double dies occur when a die receives multiple impressions from the hub, slightly offset from each other. This creates a distinct doubling effect that’s most visible in the coin’s lettering and date. The famous 1955 Lincoln cent double die shows dramatic doubling in “LIBERTY” and “IN GOD WE TRUST,” with values ranging from $1,000 to over $10,000 depending on condition.

When examining potential double dies, use a 10x loupe and examine the coin at different angles under good lighting. The doubling should appear as a shadow or ghost image alongside the primary design elements. Not all doubling is created equal – machine doubling, which occurs after the strike, lacks the raised, shelf-like appearance of true hub doubling.

Identifying Key Markers on PCGS Submissions

The Peace dollar I acquired for around $40 several years ago represents another opportunity to spot valuable variations. Mint mark variations can significantly impact value, particularly for coins from the Carson City and New Orleans mints. The 1928-S Peace dollar, for example, shows dramatic repunching in the mint mark on some specimens, with values increasing by 50-100% over standard examples.

When examining mint marks, look for signs of repunching – small traces of earlier punchings visible within or adjacent to the final mint mark. Use a reference guide to compare your specimen against known varieties. The difference between a common 1928-S and a rare repunched mint mark variety could mean thousands of dollars.

Die Cracks and Cuds: Nature’s Mint Errors

Die cracks form raised lines on the coin’s surface, while die breaks can create dramatic features. A “cud” occurs when a portion of the die breaks off completely, leaving a raised featureless area on the coin. The 1970 Lincoln cent with a dramatic die break through the date can fetch $100-$500, while minor die cracks might add only modest premiums.

Examine the coin’s rim and fields carefully. Die cracks often appear as raised lines that follow the coin’s contours, while cuds create raised, featureless blobs. The location and size of these features significantly impact their value to collectors.

Specific Errors to Look For in Your Collection

Clashed Dies

When dies strike each other without a planchet between them, they transfer design elements to each other. Subsequent strikes then show these transferred elements. The 1984 Lincoln cent with clashed dies showing parts of the reverse design on the obverse can bring $25-$100 premiums.

Mated Pairs and Multi-Struck Coins

While less common in modern submissions, coins that receive multiple strikes or are struck with damaged dies can show dramatic errors. These often command significant premiums, with dramatic examples selling for hundreds or thousands of dollars.

Off-Center Strikes

Coins struck significantly off-center show part of the design missing. The percentage off-center and whether the date is visible greatly impact value. A 10-20% off-center strike might bring 2-3 times face value, while dramatic 50%+ off-center strikes with visible dates can bring $100 or more.

Value Guide: What Makes These Errors Worthwhile

Understanding the value of errors requires knowing what collectors seek. Minor die cracks might add 10-20% to a coin’s value, while dramatic doubled dies or major mint mark varieties can multiply value many times over. The key factors are:

• Rarity of the specific variety
• Visual appeal and dramatic nature of the error
• Condition of the coin
• Demand among specialized collectors

For my recent PCGS submissions, the Morgan dollar’s scuffed holder prompted the crossover – not because of an error, but because I wanted it in a pristine PCGS holder. The Peace dollar, however, might harbor undiscovered varieties worth investigating under magnification.

Authentication and Grading Considerations

When submitting coins to PCGS or other grading services, errors and varieties require special attention. Some services charge additional fees for variety attribution, while others include it in standard grading. The cost-benefit analysis becomes crucial – as several forum members pointed out, spending $40 in grading fees on a $70 coin might not make financial sense unless you’re certain of a significant variety.

Always research current market values before submitting. Use price guides, auction records, and specialist forums to understand what varieties are currently in demand. The coin market can be fickle – varieties that commanded high premiums a decade ago might be less sought after today.

Conclusion: The Thrill of the Hunt

Error coin hunting combines historical knowledge, technical understanding, and patient observation. While my recent crossovers weren’t motivated by discovering rare errors, they represent the ongoing journey of building a collection that brings personal satisfaction. Whether you’re examining Morgan dollars, Peace dollars, or any other series, the potential for discovering something special always exists in those tiny details most people overlook.

The forum discussion surrounding my submissions highlights an important truth about this hobby: while financial considerations matter, the personal enjoyment of collecting often outweighs pure investment logic. As one collector wisely noted, if coin collecting is supposed to be about enjoyment and having fun, what’s wrong with crossing over coins you love, even if the economics are debatable?

Happy hunting, and may your loupe reveal treasures hidden in plain sight!
