Hi
Not a
Crusader coin I'm afraid.
The 'cross crosslet' is of course the arms of the kingdom of Jerusalem, but this is probably a coin of the kingdom of
Sicily under the Hapsburg rulers of
Spain (1516-1700). The kings of
Sicily were titular kings of Jerusalem as well. The
reverse on this piece is the collar of the order of the Golden Fleece, a Burgundian and Hapsburg order which wasn't founded until 1430.
Unfortunately I can't tell you any more as I have no
catalogue which covers this period.
Best wishes
Alan
