Uncle Scrooge laughed when the mysterious woman offered him one dollar for one of his dimes. But she might just have the last laugh because the dime he accidentally sold her was his lucky Number One Dime — the first dime he ever earned! — and now she's about to melt it down for one of her strange spells! Then Uncle Scrooge gets wind of a big gold-prospecting contest in Alaska, and he ropes Donald and the boys into helping him prove he's just as good a prospector now as he was back when he made his fortune. But the infuriatingly lucky Gladstone Gander decides he's going to enter the contest, too — and Gladstone never loses! And when a mysterious new planet suddenly appears in the sky on a collision course with Earth, Scrooge, Donald, and the boys are whisked there — only to discover it's filled with gold and inhabited by the ancient Norse gods! But to prevent the imminent collision, Scrooge must find a way to turn all that gold into iron — or both planets will be destroyed! Plus: the oddball inventions of the ever-eccentric Gyro Gearloose!
