Help identifying coin

[Sir Flannel-migration]

I am trying to find out any information about a coin I have has sitting in my desk for some time. I don't recall where it came from, and it has no wording that helps to its origin. Here are a couple of pictures of it. It's about the size of a U.S. dime, but has a smooth edge like a U.S. nickel. Any information would be appreciated. I don't care if it's an old bus token, just so I can find out what it is!

Thanks!!

It's a 20 Heller from Austria. Pretty common. Worth around a dollar.
