The Ethics of AI-Enhanced Numismatic Photography: When Removing Prongs Crosses the Line

Introduction: The Prong Problem

As a dedicated roll hunter and cherry picker, I’ve spent countless hours scouring through bank rolls, estate sales, and bulk lots searching for that hidden gem. But there’s one aspect of modern numismatics that has become increasingly problematic: the use of AI to “enhance” coin photographs by removing prongs from holders.

Prongs have been a standard feature of third-party coin holders since the 1980s. These small plastic fingers secure the coin in place and allow for safe handling and viewing. While they may obscure small portions of the coin’s edge, they serve an important function in preservation and authentication.

The debate over prong removal isn’t new, but AI technology has made the process nearly undetectable to the human eye. This raises serious questions about transparency in the numismatic marketplace.

Identifying Key Markers: What to Look For

Circulation Finds

When searching through circulation, you’ll rarely encounter coins in holders with prongs. However, when examining bulk lots or estate sales, you may come across coins that have been removed from their original holders. Look for:

• Small indentations on the edge where prongs made contact
• Residue from holder gaskets or foam inserts
• Discoloration patterns that suggest the coin was previously slabbed

Bulk Lots and Estate Sales

These are prime hunting grounds for cherry pickers. When examining lots, pay attention to:

• Coins that appear to have been recently removed from holders
• Inconsistent toning patterns that suggest artificial enhancement
• Images in listings that may have been digitally altered

Cherry Picking Varieties

The most valuable finds often involve varieties or errors. When examining potential varieties:

“The most important thing is to see the entire coin, including areas that might be obscured by prongs. AI removal can create a false impression of a coin’s condition or even hide varieties that exist beneath the holder.”

Value Guide: The True Cost of Deception

Market Impact

The numismatic market relies on trust and transparency. When sellers use AI to remove prongs without disclosure, they’re essentially creating a representation that may not match reality. This can lead to:

• Disappointed buyers when the actual coin differs from the image
• Questionable authentication if damage exists beneath the prongs
• Erosion of trust in online marketplaces

Ethical Considerations

The consensus among experienced collectors is clear: when selling, both pronged and de-proned images should be provided. This allows buyers to:

1. See exactly what they’re purchasing
2. Verify the coin’s condition in its holder
3. Make informed decisions about their purchase

Non-Sale Contexts

For educational purposes, publications, or casual display, the ethical lines become less clear. Many collectors argue that:

• Removing prongs for display purposes is acceptable if no sale is involved
• The enhancement should be disclosed even in non-commercial contexts
• The focus should remain on the coin itself, not the holder

Technical Analysis: How AI Prong Removal Works

The Technology

Modern AI tools can analyze the texture, color, and pattern of a coin’s surface and intelligently fill in the areas obscured by prongs. This process involves:

1. Pattern recognition of the coin’s surface
2. Texture synthesis to match surrounding areas
3. Color correction to ensure consistency

Limitations and Risks

While the technology is impressive, it has significant limitations:

• It cannot reveal damage or features that exist beneath the prongs
• It may create false impressions of a coin’s condition
• It can potentially hide varieties or errors

Best Practices for Collectors

When Buying

Always request images that show the coin in its holder, especially when:

• The price is significant
• The coin is rare or valuable
• You’re dealing with an unfamiliar seller

When Selling

Maintain transparency by:

1. Providing both pronged and de-proned images
2. Clearly disclosing any digital enhancements
3. Focusing on accurate representation over aesthetic appeal

When Collecting

For your personal collection and enjoyment:

• Feel free to enhance images for display purposes
• Keep original images for documentation
• Be honest about any modifications when sharing with others

Conclusion: Preserving Trust in Numismatics

The ability to remove prongs using AI is a technological marvel, but it comes with significant ethical responsibilities. As collectors, we must balance the desire for beautiful images with the need for transparency and honesty in our hobby.

When searching through circulation, bulk lots, and estate sales, focus on what truly matters: the coin itself. The best cherry pickers know that authenticity and condition are far more valuable than a pretty picture. By maintaining ethical standards in how we present and share our finds, we preserve the integrity of numismatics for future generations.

Remember: a genuine coin with honest wear is always more valuable than a digitally enhanced representation of something that never existed.
