Not quite confederate money

Our neighbor Weezie was interested in the original nails — handmade — from the original house construction. So Paul has been careful to preserve a few. Apparently, they can break easily so keeping them intact takes a little bit of care. Here are what some look like:
That 50 coin? We have no idea what it is. We’re hoping someone might know? It was inside the original wall. It’s not quite wood, but it’s not plastic either. I’m hoping that it’s identity is more interesting than that of a poker chip. (We’re still waiting to find the vault of confederate money.) It has sort of a purple color to it and the lettering it sort of golden. Anyone have any ideas?
