Hello- I am not very familiar with different kinds of mint errors, but I came upon this weird 1980 dime which has absolutely no trace of reeding on its edge. It doesn’t appear that the edge has worn smooth, it looks as if there has never been any reeding at all on the coin. Also, the edge also is disproportionately thick compared the the rest of the planchette. Is this some kind of minting error, or just some weird uneven wear? Thanks.
Like @Spark1951 said, it's been "spooned". The reeded edge is created when a coin is struck, so this had to have happened after it left the mint.
Imagine spending 10's and 100's of hours banging the sides of a dime with a spoon and it's ultimately worth nothing. Wouldn't building a machine to do that, much like a rock tumbler smoothen and polishes rocks, be easier? And getting that dime distorted all the way around so perfectly evenly round by hitting it with a spoon is beyond accurate. Talk about standing around watching paint dry.
