It has come to pass that a unique 1946-D Roosevelt Dime with designer initials UJ instead of JS has recently surfaced. Mint spoksperson Ernestine Chortle reports that Chief Internal Investigator Lt. Columbo believes the UJ stands for Uncle Joe.This would confirm earlier suspicions that JS was really a shout out to Joseph Stalin. The UJ, as Ernestine goes on to explain, was probably the original prototype but they couldn't disguise it as someone else because Ulysses Grant has been dead for so long, she snorted. Social Media experts believe the oddity could be worth between 10 million and one billion dollars. It depends on whether it's an ordinary full split band or the more exciting fully rounded full split bands.
