Help identifying a coin (unknown anything) [solved]

Greetings,

I have a friend that has a coin he has collected and sat for years sealed. He thinks it's made of copper. From the picture, you can tell it's very hard to determine what it is all about. It is about the size of a US dime (approximately 18 mm) and he says it's very thin... about as thin as an index card. Any help would be appreciated. No weight provided.

This. Or very close to it. Very hard to determine exactly with condition and photos provided.

I think that is it. If not, it's extremely close. I can see the cross/crown pattern. Very quick response and help Thanks Harry!
