Identifying an ancient gold coin

Hello everyone.

Fist of all, sorry for my bad english.

I'm looking for help for identifying, I guess an ancient gold coin.
A friend of mine, send me these two pictures. I know that the quality is not good, but this is what I have for now.
I asked one my colleague wich is numismatist, but from the pictures he can't give me any guidelines.
Looked at alot of gold coins and I think it is from Ancient Roman. So I hope here to get something.
Pictures:

Measurements - diameter and weight?
Images cropped ...

I doubt this is gold or ancient, looks like a badly damaged modern token but weight and diameter should clear things up.

Hello guys, Thank you for your fast response.

I' m waiting for dimension information from the owner.

About the material and ancient or not, I'm not competent. I write what I think it is, sorry if I let you down.

Looks too round to be an ancient hand-struck coin.
