Frequently Asked Questions
What causes die clashes?
Die clashes happen when no planchet feeds between the dies during a strike cycle. The two dies hit each other directly, transferring mirror impressions that appear on subsequent coins as ghost images.
Are die clash coins valuable?
Minor clashes add $5-$25 to a coin's value. Dramatic clashes with clearly visible ghost design elements can be worth $50-$300+ depending on the coin type and severity.
How do I identify a die clash?
Look for faint design elements in the flat field areas that do not belong. These will be mirror images of the opposite side's design. Upload to ErrorHunt for AI detection.
