Roman Coin ID [решено]

Can some one help me identify this coin, please?

It is 17mm in diameter, 3mm thick, it weights 3.14g, coin aligned. I know this one is hard becasue it is heavily worn out. No legible words and only hint of what looks like a bust facing right on both sides.

I believe it might be RPC 3102 (Agrippina II) or something similar.

Thank for the help,

Carlos

Probably not identifiable, and we would need much better pictures anyway, but this search produces some similar coins. I suppose it's a denarius given the weight and diameter, but I can't be sure.

The same search could be repeated for other emperors (the one I did is Caligula).

Thank you Camerinvs.

Another piece of information is that it is made of a yellow metal, something like brass/bronze.

Cheers
