"The Secret of Atlantis" reprints Uncle Scrooge #5, March 1954 and marks the first appearance of the Junior Woodchucks' Guidebook (as it was later known). It also shows insights into Barks' mind concerning collectibles: this time it's a 1916 quarter that Scrooge manipulates into being the rarest and most valuable coin in the world - and he owns the only one!
