I do not see anything unusual with the
style relative to other examples I could find.
It is a precise match to this specimen on
RPC Online:
http://rpc.ashmus.ox.ac.uk/coins/3/6074/What troubles me is that:
1. There appeared to have been some initial doubts about the example on PRC Online, which clicking on the image, shows it to be from
BnF.
2. Your coin appears to match the coin in more ways than a die match on the
reverse, look at the positions on the edge splits. There appear to be some differences on the
obverse however but very similar.
Thus, it would appear to me that your coin could be a
cast copy of another one.
If I am correct in this assessment, then does this
cast further doubt on the authenticity of the
BnF coin...?
Or I could be way off as really hard to be certain from the photos.
