It's a Magician's coin or, maybe a spy coin.
It's made in a machine shop by carefully cutting/grinding away at a coin to make the hollow spot and then cutting and grinding the opposite on another coin.
You can find them for sale at ThinkGeek.com. I think they sell for about $30 so I am surprised that it ended up out in the wild.
Then again, maybe it's a homework assignment for a shop class somewhere and the student didn't want it anymore.
I have one made from a quarter and I also have a double headed quarter.
Anyway, they're fun to have and you can always use it to hide microfilm. LOL
