My guess, Replica Roman coin

Hi everyone

I would like to add this to the Numista  library,  could someone tell me how to list it

My guess would be Roman Empire, what are your thoughts?

The weight is 7.1 grams, it is approximately 24 Millimeters, I do not know the composition, I doubt it is silver, but I am not sure how to tell

Thanks in advance 

Why a replica should be added o the catalog? I fear confusion. I'm no expert, but I'm quite sure, that your coin is a replica; I could not find a similar(weight and size) from this time.

A modern production inspired by Sestertius and Dupondius of Trajan but it is not a genuine coin; then not to be added to the coin catalogue.

I wou not ask to add it to the coin category, I would put in Exonumia as a modern copy
