Found this 1991 Lincoln while roll searching. This looks quite interesting. Definitely need some seasoned error specialists to give me an opinion on this one.
Altered Cent. Vise job. Someone used a vise or other tool to press the edge from one Cent to your Cents edge. Evidence is incused and backwards lettering.
That thought occurred to me. But I have a question: Do we ever see two coins overlapped in a coin press where the same thing occurs - with one coin pressed into the other? If so, how can I tell the difference between a mint caused reverse impression and a garage job by some trickster?
Asking the right people with experience the questions you have. Also knowing how true mint errors occur.
PMD. Someone hated that Lincoln enough to mutilate it. As for your other question; "If so, how can I tell the difference between a mint caused reverse impression and a garage job by some trickster?" Think about the minting process. The planchet is held in place with the collar while being pressed between the dies. That being said, how would an already minted cent leave an impression on the new planchet being minted?
OK….I get it now. Thanks for walking me through that. I think I must have been thinking more of a brockage type error as I seem to recall seeing a photo of one once where the letters were backwards. But, honestly, brockage errors drive me nuts when I read the explanations on how those happen.
