Coin Talk

me and my mom found two of these in a box of old jewelry, they look tarnished but were looking for information about it. can anyone help? it looks like it might be bronze or gold but is definately old. it has a cross on one side with symbols within the squares of it, has words around the border but cannot make out what they say, i think they are cut off. the other side has s symbol and has lettters and numbers within it and says EXANO 1736. can anyone help me who i should take it to, how much it might be worth, and its history? i tried to post a picture of it but cannot figure out how
