You are most likely talking about a Morgan Dollar, there are many rare dates/mintmarks. You need to provide the date of the coin and the mintmark (found on the reverse under the wreath, some coins have no mintmark but it will either be O, CC, S, or D if there is a mintmark) without knowing that I can't tell if you have a $22 coin or a $220 coin.
