The penny error checker is optimized for Lincoln cents — the most collected and searched U.S. coin series. Upload photos of your pennies and the AI will check for doubled dies, off-center strikes, die cracks, clipped planchets, wrong planchet errors, and other anomalies specific to the penny series.
More error coins are found on pennies than any other denomination. The sheer volume of pennies produced — tens of billions over the decades — means more opportunities for errors. Lincoln cents have been struck at multiple mints with hundreds of different die pairs, producing a rich variety of die varieties and striking errors.
Penny errors can be subtle, especially doubled dies. For the best scan results:
The most commonly found penny errors include minor die cracks, grease-filled dies, and small off-center strikes. More significant errors like doubled dies, major cuds, and wrong planchet strikes are less common but more valuable.
Take a clear, well-lit photo of your penny (both sides if possible), upload it to ErrorHunt's scanner, and receive AI analysis within seconds. The system checks for all major error types specific to Lincoln cents.
Errors can occur in any year. Some years are better known for specific varieties (certain doubled dies, for example), but errors are not limited to any particular time period. Checking pennies from any era is worthwhile.
