Can you tell if the dime design is incuse or not? It looks like it's a vise job where the coins are compressed on one another. For a coin to have a legitimate double design a mint associate would have to create it by unnatural means. But stranger things have happened...
It's probably impossible for such a coin to be accidentally created at the mint like that. Some of the lettering looks reversed.
IMO someone outside of the Mint went to a lot of trouble to create that. Considered damaged, not a mint error. Combination of a vise job and only the one who made it knows what else.
The OP created multiple threads https://www.cointalk.com/threads/2016-nickel-error.347849/ It is a vice job. Damaged.
It is a nickel that has had a dime glued to it and then the dime removed leaving the incuse impression of the dime in the glue. Look closer, you can see bubbles in the glue. Not a vise job.
