Up for sale is a rare 1972 Kennedy Half Dollar with a unique error that is highly sought after by collectors. This coin has the FS-901 error, also known as the "no fg" reverse error, which means the designer's initials on the reverse side are missing. The coin was minted in Denver and is uncertified. It is important to note that this coin has been circulated, but despite its age and history, it is in great condition. This is a must-have for any serious collector of US coins and paper money.
