Okay, all joking aside. It's very difficult to tell what it is from where we are sitting. Give us the weight in grams. What size coin is it closest to? Does it like, feel or sound like silver? Where did you get it? What do "you" think it is? We need a little more help from you.
I found it in a storage locker i bought along with some other old coins. They were in a avocado green Tupperware container inside a box with a few other vintage items aswell.
