Hello, i've found a coin recently. It's probably celtic, the symbol on one side is shamrock(clover) for sure, 4 sided. Metal that coin is made from is probably silver, metal has some kind of green corrosion on it. If anyone knows where the coin comes from, date etc.. I would be greatful if you could get me some information about it. Pics here
It might be a "Celtic Cross" or "Celtic Knot" token of some kind. Better pictures would help, along with the inscription text.
