I would like a bit of input on the authenticity of this coin which I am not sure of. The weight of the coin is 3.9 grams, which is fine, but the edge of the flan shows what appears to be filing and the overall appearance of the coin seems quite a bit different from my other Republican denarii. If you see any flaws could you please tell me what the flaw s look like to you. Thanks
Hard to say without seeing the coin in hand. Can you see casting pearls on the obverse? I generally don't like file marks on the edge.
I am in no way qualified to render an opinion. It seems similar to one of my RR Denarius. I have mine that I can lay out there for you to see... RR Junius Silanus 91 BCE Roma B behind Biga I above Sear 225 Craw 337-3
I have seen fake Roman Republican denarii with excellent details and convincing surfaces but square or filed edges. The third and fourth photos of the OP coin make me think it is a modern fake.
