Possibly part of a cylinder type door lock?

Looks kinda like part of a coin mechanism out of a rotory vending machine, perhaps a gumball machine.

That is a possibility due to where it was found. Only a dime fits in there.

first thing to pop into my head...some sort of old skate key or adjustment tool..

I've seen this before. I think from under a certian brand of kitchen faucet.
