Over here we see that Scrooge has a pretty unque skill that he can swim through money.
In the entire Duckverse (Ducktales, Barks etc.) do we ever see anyone else with this skill?
There was a Carl Barks comic in which Magica de Spell, having magically swindled Scrooge out of his hoard (as she often tried to do), was able to swim/move through the sea of cash. Her capacity can probably be attributed to magic, obviously.
