You are a little spare on information. What country is it from? Does it have a denomination or an inscription on it? What is the diameter? What is the design on both sides? Is it a coin, a medal, a medallion or an IOC souvenir?
I don't know the weight of a coin but it varies by which coin you are weighing.
