Uncovering Hidden Treasures: A Collector’s Guide to Error Coins at the Spring PNNA Show

Introduction: The Devil’s in the Details

Most people look right past the tiny details that can turn a common item into a rarity worth thousands. As an error coin hunter, I’ve spent decades training my eyes to spot the subtle variations that separate ordinary pocket change from numismatic treasures. The Spring PNNA show represents one of the best opportunities to examine coins up close and discover these hidden gems.

Historical Context of the PNNA Show

The Pacific Northwest Numismatic Association (PNNA) show has been a cornerstone of the regional collecting community for decades. Originally held in Seattle, the show recently relocated to Portland, Oregon due to Washington state’s implementation of sales tax on coins and bullion. This move has created a fascinating dynamic where collectors must now weigh the value of attendance against increased travel time and expenses.

The Tax Factor

The sales tax implementation in Washington has had ripple effects throughout the numismatic community. Many collectors, particularly those from Seattle who previously enjoyed a convenient show location, now face a three-hour drive to Portland. This has sparked considerable discussion about the true cost of collecting and whether the potential finds justify the journey.

Key Error Types to Hunt For

Die Cracks: The Spiderweb Effect

Die cracks appear as raised lines on a coin’s surface, created when the die itself develops fractures during the minting process. These cracks fill with metal during striking, creating distinctive raised features. Look for:

• Thin, irregular lines that may appear to radiate from design elements
• Areas where the crack has caused metal to flow abnormally
• Progression of cracks across multiple die states

Double Dies: The Mirror Image

Double die errors occur when a die receives multiple impressions from the hub, slightly offset from each other. This creates a doubled appearance in the design elements. Key indicators include:

• Letters or numbers that appear to have shadows or ghost images
• Design elements that seem to repeat slightly offset
• Most valuable when the doubling is dramatic and easily visible

Mint Mark Variations: The Tiny Details That Matter

Mint marks can vary significantly between dies and years, creating valuable varieties. Pay close attention to:

• The size and shape of mint marks
• Position relative to the date or other design elements
• Repunched mint marks where the mark was stamped multiple times
• Overmintmarks where one mint mark was stamped over another

Specific Series to Examine

Lincoln Cents: A Treasure Trove

Lincoln cents offer some of the most accessible error hunting opportunities. Focus on:

• 1955 Double Die Obverse – the king of Lincoln cent errors
• 1972 Double Die varieties
• 1983 Doubled Die Reverse
• Various die break varieties, especially on memorial building

State Quarters: Modern Errors Abound

State quarters have yielded numerous valuable errors since their introduction. Look for:

• Extra leaf varieties on Wisconsin quarters
• Double die reverses on various states
• Wrong planchet strikes
• Off-center strikes

Authentication Techniques

Magnification Essentials

Proper examination requires adequate magnification. I recommend:

• A quality 10x loupe for general examination
• A 30x microscope for detailed analysis of suspected errors
• Proper lighting to reveal subtle variations

Red Flags and Fakes

Not everything that appears to be an error actually is. Be wary of:

• Post-mint damage that mimics errors
• Altered coins passed off as errors
• Machine doubling mistaken for hub doubling

Value Considerations

Factors Affecting Value

The value of error coins depends on several factors:

• Rarity of the specific error type
• Visibility and dramatic nature of the error
• Condition of the coin
• Demand among collectors
• Historical significance

Price Ranges

Common errors might bring only a small premium, while major errors can command thousands:

• Minor die cracks: $10-50 premium
• Moderate double dies: $100-500
• Major errors like 1955 Double Die: $1,000-5,000+

Show Strategies

Preparation Tips

Maximize your show experience with these strategies:

• Research which dealers specialize in errors
• Bring proper tools (loupe, gloves, reference materials)
• Arrive early for the best selection
• Network with other error collectors

What to Bring

Essential items for error hunting:

• Quality magnifying equipment
• Notebook for recording finds
• Price guides and reference books
• Gloves to protect coins from oils

Conclusion: The Thrill of the Hunt

While the relocation of the PNNA show has created logistical challenges for many collectors, it also represents new opportunities. The Portland area offers a fresh pool of coins and dealers, potentially bringing new error varieties to light. Whether you’re examining rolls of cents or carefully studying high-grade specimens, the principles of error hunting remain the same: patience, knowledge, and attention to detail. Remember, the next great discovery could be hiding in plain sight, waiting for a trained eye to recognize its significance. Happy hunting!
