1917 Five Stadtvren coin or token?

I found this in a job lot I bought. Is it a coin or a token - both sides are the same.



Thanks Dave.

   That is the 1918 coin, and it is in the Tokens section.
Not sure if the F# 105.6 means only that 1918 date, so a new page would have to be created for your 1917 - or maybe just needs 1917 adding to that existing page.
