I have a 1996 penny that I believe is double die and incorrectly stamped. Please confirm whether the features are errors or from wear and tear.
Some people might make a dollar or two selling these on eBay, but generally they aren't worth all that much. Albeit, they are interesting to see and to help understand the minting process further.
Worn Die Strike. Struck through grease letters and numerals. Die Deterioration strike. Neat but nothing major
