I believe this to be a genuine Mint error. This is a finished dime that accidentally got into a hopper with cent blanks. The dime was struck with Lincoln cent dies, almost obliterating the dime’s design. You can see some of the dime under the cent. Note the reeding on the edge. Reeding is impressed by the collar that holds the coin when it is struck. Dimes have a reeded edge, cents have a plain edge.
This type of error is valuable and should be stored in a Mylar flip and not handled. Do not clean the coin or wipe it, that will reduce its value. Estimate (this is a guess): $500+.
