Identifying roman coin (bad quality) [opgelost]

Hello, 

i need help identifying another roman coin. I find this coin extremely difficult to classify even approximately. I apologise for the poor condition of the coin, but perhaps someone will be able to identify it. :)

Thanks

Diameter: 13mm 

Weight: 2,1g

Maybe is greece ancient?like this..

Very good call. Thank you. However, I wonder if the weight can vary so much, or if it is a similar coin to the one you selected.
