I have no idea what it could be from, but the person told me that it is at least 100 years old. It is light and it seems that it may be made of silver.
Just out of curiosity, what makes you think it is a token? Technically speaking, a token is a substitute for money and would generally have a value on one side. Your piece looks like a pendant to me.
