Superbaby dug up a chunk of gold that led to the California Gold Rush and helped Jason retrieve the Golden Fleece (including taking the heat from a dragon) in one adventure just because he was looking for gold because Ma Kent lost an earring!
Which comics were these published in, MEL?
I certainly don't recall ever reading the Golden Fleece story, at least.
Perhaps my favorite Superboy story is
The Three Ages of Superboy!, from
Superboy #103 (March 1963) - by the great trio of Edmond Hamilton, Curt Swan, and George Klein - a full-length tale, which has Superboy traveling back through the time-barrier to ancient Egypt, the time of King Arthur, and the old west of Jesse James, respectively.
There was also a less memorable story where he goes back and meets the
very unhistorical Ben Hur.
