I have this laying around from a long long time ago. Any ideas what this could be?

I'd guess quartz with an iron stain. You can remove the stain on the outside with Super Iron Out. Do you know the hardness? Or are you asking about the coin? hehe

This is a look at the other side. I am not sure of the hardness.

can it be scratched with a pocket knife? If so I would say travertine. If not then quartz would be my next guess. It is all about the hardness.
