Probably just someone playing around. I have done similar things to coins.

In fact some of the lathe books tell you to take a coin "since its round" and use it as a chuck guide for setting the lathe for x size on the chuck.

My little watch lathe recommended a nickel or quarter. maybe a larger lathe recommended a half?
Fun find!

It looks like it was the start of a magicians coin that didn't get finished. I found one like that. All that was left was the very center on one side. I saw how they do it on TV in a lathe.
