 It is never made clear whether the dime actually brings good luck or if Scrooge merely believes in it so much that he is distressed and makes bad decisions whenever he no longer has the dime.Since Barks never actually said that it was because of the coin that Scrooge was the richest duck in the world, Don Rosa, after various informational exchanges with Barks, for a faithful production of Life and Times Of Scrooge McDuck, clarified that The Number One Dime is not actually an amulet, and that this vision was just a myth.The Number One Dime is just a sentimental object that happens to be the first coin Scrooge received for his work.
