Exactly. There are some rare examples where dime was accidentally struck at the Mint with a cent die; those are valuable. On those coins, though, the cent design doesn't show up mirror-reversed like it does here, and since the striking takes place on both sides, both sides show the overstrike. On yours, the reverse is flat, either because it was squeezed flat in the vise or because they did something else to it.
Yes, most certainly. Somewhere out there is a penny with one smooth side and a reverse with a dime smashed into it.
It's a dime. Put a penny next to it, wrap it up and put it in a vise. Tighten the vise and your dime is the result.
I guess I better not mention a certain name ......who had an 11 cent coin....... beetlejuice,beetlejuice ,beetlejuice . .....
