Decadrachm - Authentic? Fake?

Each of the above uses the term. Skip definition 1 below but note use for structures. I'd say it is the structure of the coin.

Sorry to inform you, but your coin is certainly not the same type as the one pictured earlier in this thread.

Here is a type which is closer to your coin:




See the difference in the style of the quadriga? And the male head without any dolphins around?
Btw, this type is from Katane in Sicily.

Your coin looks rather like base metal, what is the weight and the diameter?

Somehow the patina looks a little dubious, but based on the picture I cannot make a definite comment.

Please note, that I said the posted sketch is more similar to your coin than the other posted. The sketch is from Plant, a guide for helping to identify ancient coins. Unless one finds a real match one cannot fully attribute the coin.

With the ancient drachm having a weight around the 4.2g mark, your coin doesn't fit into any of the standard categories. From the picture I would suspect anyhow that it is not silver. Is it an authentic ancient coin? Cannot say for sure but I have serious doubt since the patina looks rather painted on to me - but wait to hear what others have to say.
