How to Spot Rare Errors on Spring PNNA Show report

Historical Significance

Most people overlook the tiny details that can transform a common coin into a rarity worth thousands. The Spring PNNA Show report provides an excellent case study in understanding how error coins and varieties can dramatically impact numismatic value. At this particular show, held in Portland after moving from Tukwila, collectors and dealers gathered to showcase everything from common wheat cents to rare national bank notes.

The Evolution of Error Coin Hunting

Error coin hunting has evolved significantly over the decades. What began as collectors noticing obvious mistakes has transformed into a sophisticated field requiring knowledge of minting processes, die states, and production anomalies. The Spring PNNA Show exemplifies this evolution, with dealers like Daryl from Bellingham Coin Shop bringing decades of expertise to identify and authenticate potential errors.

Identifying Key Markers

Die Cracks and Cuds

Die cracks are one of the most common and valuable error types. These appear as raised lines on the coin’s surface where the die has fractured. At the Spring PNNA Show, several dealers noted interesting die cracks on various pieces. When examining coins for die cracks:

• Look for raised lines that appear to be part of the design but don’t match any known features
• Check the edges of letters and numbers, where stress often causes cracking
• Examine areas around the date and mint mark, which experience the most pressure during striking

Double Dies

Double die errors occur when the die itself is struck more than once during its creation, resulting in a doubled image on the coin. The most famous example is the 1955 Lincoln cent double die, which can command thousands of dollars in mint condition. To identify double dies:

• Use magnification (at least 10x) to examine the coin’s details
• Look for doubling in the date, lettering, or design elements
• Check if the doubling appears on all elements consistently (this confirms it’s a genuine double die rather than machine doubling)

Mint Mark Variations

Mint mark variations can significantly impact a coin’s collectibility and value. At the Spring PNNA Show, several notable examples were discussed, including the Bellingham, WA $20 national bank note that was described as “fairly difficult.” When examining mint marks:

• Compare the mint mark to known authentic examples
• Look for repunched mint marks (RPMs), where the mint mark was stamped more than once
• Check for over-mint marks, where one mint mark was stamped over another

Specific Errors to Look For

The Spring PNNA Show showcased numerous error types. Based on dealer reports, here are specific errors to watch for:

1. Off-center strikes – where the coin is struck away from the center
2. Broadstrikes – coins struck without the collar, resulting in a larger diameter
3. Wrong planchet errors – coins struck on incorrect metal blanks
4. Die adjustment strikes – coins with weak strikes due to die adjustment
5. Clashed dies – where dies strike each other without a planchet, transferring design elements

Value Guide

Factors Affecting Error Coin Values

At the Spring PNNA Show, dealers reported that error coins sold exceptionally well. Several factors determine value:

• Rarity – How many examples are known to exist
• Visual appeal – How dramatic and noticeable the error is
• Condition – Higher grade examples command premium prices
• Demand – Popular errors with collectors tend to bring higher prices

Price Ranges for Common Errors

Authentication and Certification

The Role of Third-Party Grading

At the Spring PNNA Show, several dealers mentioned submitting coins to PCGS for authentication. Third-party grading is crucial for error coins because:

• It provides expert verification of the error type
• It protects against counterfeits and alterations
• It establishes a certified grade that affects value
• It provides liquidity when selling

Red Flags to Watch For

Several dealers at the show shared experiences with problematic submissions. Watch for these red flags:

• Post-mint damage that resembles errors
• Altered dates or mint marks
• Artificial toning to hide problems
• Coins that seem too good to be true

Tools of the Trade

Essential Equipment

Successful error coin hunting requires proper tools. Based on what dealers were using at the Spring PNNA Show:

• High-quality magnifying glass (10x-20x magnification)
• Digital microscope for detailed examination
• Proper lighting (LED lamps with adjustable intensity)
• Precision scales for weight verification
• Calipers for measuring dimensions

Reference Materials

Dealers at the show emphasized the importance of reference materials:

• Specialized error coin catalogs
• Online databases with high-resolution images
• Membership in error coin specialty clubs
• Networking with experienced collectors

Young Collectors Making Waves

One of the most encouraging aspects of the Spring PNNA Show was the presence of young collectors. A 12-year-old numismatist impressed dealers with his ability to quickly assess coins and make informed decisions. This highlights the importance of mentoring the next generation of error coin hunters.

Conclusion

The Spring PNNA Show report demonstrates that error coin hunting remains a vibrant and rewarding specialty within numismatics. From identifying subtle die cracks to recognizing dramatic double dies, the field offers something for collectors at every level. The show’s success, with dealers reporting some of their best sales ever, indicates strong ongoing interest in error coins.

For those looking to start their error coin hunting journey, remember that education is paramount. Study reference materials, examine as many coins as possible, and don’t be afraid to ask questions of experienced collectors. The tiny details that most people overlook could be your pathway to discovering a rare and valuable error coin.
