I'm not an expert in any kind of coins, but I reckon I'm good at research and will do my best to help. Feel free to tell me my identifications/valuations/gradings are wrong. It's the only way I'll learn.
I might look at this coin closer so i can be sure about the type. It seems there is more informations about it using Numista's english version Vs the french one.
