Uncle Scrooge Bargain Book: Walt Disney's Comics in Color #4

When Scrooge McDuck sinks nearly every 1916 quarter in the Atlantic to make one rarest coin on Earth, he’s forced to dive deep after the final one is crushed—only to stumble upon the long-lost city of Atlantis, home to fish-men who thrive beneath the waves. With Donald and the nephews in tow, Scrooge’s treasure hunt takes a surprising turn as ancient wonders and underwater secrets rise from the ocean floor.

When Scrooge promises to match the ducks’ donation for a Christmas dinner and a toy train for Shacktown’s children, the holiday spirit takes a nosedive—literally—when his money bin collapses, sending his fortune plummeting into a cavern beneath his mansion. Now, with the money trapped just above a bottomless pit, Daisy, Donald, Gladstone, and the nephews must find a way to keep Scrooge’s promise before Christmas Eve.
