How to Spot Rare Errors on Roll Call Manchester NH Coin Show Fri and Say

The Hidden Treasures in Your Pocket Change

Most people overlook the tiny details that can transform a common coin into a rarity worth thousands. At the Manchester NH Coin Show, collectors from across New England gather to hunt for these hidden gems, but the real treasure hunt begins long before you reach the convention floor. Understanding how to identify die cracks, double dies, and mint mark variations can transform your collecting experience from casual browsing to targeted treasure hunting.

Understanding Die Cracks: The Fingerprint of Error Coins

Die cracks are among the most common yet valuable errors you’ll encounter. These appear as raised lines on the coin’s surface, created when the die itself develops a fracture during the minting process. Unlike scratches or post-mint damage, die cracks have a distinctive raised appearance because they’re formed during the striking process. Look for these telltale signs:

• Raised lines that follow the contours of the design
• Cracks that appear to flow through lettering or design elements
• Multiple connected cracks forming “die break” patterns
• Especially valuable are die cracks that create unique shapes or patterns

Double Dies: When the Mint Makes the Same Mistake Twice

Double die errors occur when the die itself is struck twice during the hubbing process, creating a doubled image. These errors are particularly valuable because they’re consistent across all coins struck from that die. The key to identifying double dies is understanding that the doubling appears on the coin as raised elements, not as incuse marks. Examine areas like:

• Date numerals
• Mint marks
• Lettering and inscriptions
• Portrait features on the obverse

Mint Mark Variations: The Collector’s Gold Mine

Mint mark variations can be subtle but highly significant. At regional shows like Manchester, you’ll find dealers specializing in specific mint mark varieties. Pay attention to:

• Size differences in mint marks
• Position variations (high, low, left, right)
• Different mint mark styles used in different years
• Re-punched mint marks showing traces of previous placement

Regional Show Advantages for Error Collectors

The Manchester NH Coin Show offers unique advantages for error coin hunters. With no sales tax on coin purchases, as confirmed by multiple attendees, you can maximize your collecting budget. The show attracts dealers from across New England, bringing diverse inventory that you won’t find at local shops. As one collector noted, this show and the NENA show in Milford, MA are considered two of the best regional shows in New England.

Strategic Show Attendance

Timing your attendance can significantly impact your success. Dealer setup day, typically Thursday, often provides the best selection before the crowds arrive. Many serious collectors arrive early to examine new inventory. Consider these strategies:

• Arrive early on setup day for first pick
• Purchase tickets online to avoid lines
• Network with dealers who specialize in errors
• Bring proper lighting and magnification tools

Authentication and Grading Considerations

When you discover a potential error, proper authentication becomes crucial. Several collectors mentioned plans to submit coins to ANACS, highlighting the importance of professional grading. Before submission, examine your finds carefully:

Remember that not every unusual feature constitutes a valuable error. Post-mint damage, die deterioration, and strike doubling can mimic true errors but lack collector value.

Key Areas to Examine

Develop a systematic approach to examining coins:

1. Check the date for doubling or repunching
2. Examine mint marks for size and position variations
3. Look for die cracks, especially on high points of the design
4. Check lettering for signs of doubling
5. Examine the rim for signs of collar errors

Seasonal Show Schedule and Planning

The Manchester show schedule has evolved, with the fall show now occurring in early December. This timing can be advantageous for collectors looking to complete year-end collections or find holiday gifts. Plan your attendance around:

• Dealer inventory cycles
• Tax planning for larger purchases
