It is bigger than a quater and is from 1970. it has the words Kwnctantinoc Bacixeyc twn eaahnwn on the front along with the picture of a head. i'm sure if that is totally right due to not having symbols. On the back: two guys holding swords on each side of a shield with the number 5 underneath. Then it says something way wierd Any leads would be awsome. Thanks.
