Identification of this Coin

Afternoon. I found this nickel while working at a store and took it from the cash register, not stealing, the boss was there, he said, just swap it out so the drawer balances....it was a one-man run liquor store, so I had a lot of freedom. I can't imagine this is anything special. Has anyone else come across something like this?
