Quarters ad dimes, and lager denominations of coins, used to be made of silver, and a few of gold. The value of each coin was basically determined by the value of the silver or gold used to make it. Some people used to shave bits off each coin they received, thus accumulating valuable silver and gold for resale while reducing the real value of the coin being shaved.

You need to be more specific on the date of your coin and the country of origin. For example, some $2 coins are real gold, such as the Newfoundland 2 dollar gold coin which is 22K gold. On the other hand, there are many $2 coins that aren't real gold, for example Australia's modern $2 coin looks golden but contains no real gold, neither does Canada's modern $2 coin. If you are unsure about if your $2 coin contains gold, post a new question including the date and the country of origin.
