I have this coin that is made of copper that I think is supposed to be a Gold coin. It may be someones attempt to make a forgery I do not know. It is quite bizarre on the reverse. It looks to be completely corroded away. If anyone is interested in having a closer look I would be happy to send it to you. It does not fit into any of my collecting, so I would like to be rid of it. I cannot bring myself to toss it out without at least offering it up here. The obverse looks like a legit coin, but what do I know of a 1400's coin. The only info I found. An agnel of Philip the Fair An agnel, aignel, agnel d'or or mouton d’or was a French gold coin, invented by Louis IX of France in the 13th century. The first known examples were struck under Philip the Fair from 26 January 1311 onwards. The obverse of the coin showed the Paschal Lamb or Agnus Dei, which gave the coin its name. The reverse showed a Gothic cross. The last agnels were struck under Charles VII of France in the 15th century.
Interesting piece. Maybe (just maybe?) there wasn't anything on the other side to begin with. Perhaps it's a uniface striking (or casting, even), and that other side is just ... well ... bubbly, for lack of a better word. This could be the case if it was a casting. I don't know. The Agnus Dei is a pretty common motif on European coins and medals of the Renaissance and early modern eras.
