The story writers were forced to read “Life and Times of Scrooge McDuck” by Don Rosa for the show, to really understand the version of this microverse they were supposed to create. Which makes this story very interesting, because one story Don Rosa wrote, wich initially got rejected, until he could draw it for a different Disney-Comic (I believe a french one), was “The Coin”, which basically shows more or less a day in Duckburg from the “eyes” of a coin, that Scrooge accidentally gives Donald, and tries to retrieve the entire day. It has some similarities to this story, though obviously it involved Scrooge more, and the coin switched possession between him, Donald, Gladstone Gander, the triplets, the Beagle Boys and Gus Goose.
The story of how he got the Number One Dime is from Don Rosa as well (or: He connected the dots of Scrooge being a shoeshine, and this being how he got the coin). And he penned the thought, that the slight continuity error of a Scottish Scrooge having earned an American Dime first was actually not an error, but what motivated him to go to America (and be sceptical of others more)
