Templar:
Here are my guesses:
The cross appears either Italian or French. I'll choose French for what I see on the coin's obverse; the letters that seem to read...RISL........
There is an area in Normandy, France called Risle. Montfort (of Crusader fame) was from this area. A castle in Palestine, in the Crusader Kingdom of Arce, is still named after Montfort. I'd stay on that research path if I didn't have to first find a way to pay my late rent.
Don..
