Is a 1972 one dollar coin with the eagle upside down on back worth more?

No, a 1972 one dollar coin with the eagle upside down on the back is not worth more. In fact, it is not a valid coin at all. The United States Mint has never produced a one dollar coin with the eagle upside down on the back. If you come across a coin like this, it is most likely a counterfeit or a novelty item.
