In the fictional Scrooge McDuck universe, the Number One Dime is the first coin that Scrooge McDuck ever earned. According to The Life and Times of Scrooge McDuck, Scrooge earned the dime when he was ten years old. Before that belonged to Howard Rockerduck (the father of John Rockerduck). Scrooge still has the dime and keeps it on a pillow under glass because it is very special to him. It is only special because it is the first coin he earned even though Donald Duck, Huey Dewey and Louie, and Gladstone Gander among many others think it is really a lucky charm. Magica De Spell believes the dime has magic powers inside it and she tries to steal it from Scrooge so she can melt the coin into an amulet for herself. The Number One Dime first appeared in Uncle Scrooge#3 in the story titled "The Round Money Bin", which was written in 1953 by Carl Barks.
