I have bought this coin a few years ago, but I'd like to get an accurate idea of its value. For some reason, NGC lists pretty much all mintmarks except M, which is the one I happen to have.
Here is a link to the coin's page on numista: N#23333
Lighting was not particularly good and my phone's camera isn't the best, so I hope the two amateur pictures will suffice. The coin is in pretty good shape as only the highest details seem to have started to wear down. It also has somewhat of a mint luster, especially on the obverse (the side with the coat of arms).
Thank you in advance!
