I just recently started collecting, but I already had a few coins from travels. While cataloguing those coins, I found an Arc de Triomphe toke, similar to this one: https://en.numista.com/catalogue/pieces42384.html. However, it is undated and the back is plain, instead of decorated, so I can't properly catalogue it yet.
I know for a fact it is real, before anyone asks. Here is the coin itself: http://imgur.com/a/RK4ap (sorry for the poor image quality).
Any help is appreciated!
