This version of Scrooge McDuck was rebuilt in the 21st century on an island not far from Duckburg, linked to it by a bridge. The Bin contains multiple levels, including the underground laboratory of Gyro Gearloose, and McDuck only built it in the middle of the Duckburg Bay in the secure knowledge that it was "earthquake-proof, tsunami-proof, and giant-reptile-proof".
The Other Bin
Unlike his Prime Universe self, Scrooge McDuck does not keep his more dangerous or cursed treasures in the Money Bin, but instead scatters the milder ones in his Manor and keeps the rest locked away in the "Other Bin", a super-secure underground complex beneath the Manor.
Behind the scenes
This version of the Money Bin appears in DuckTales 2017, beginning with Woo-oo!. It also received a cameo in a regular Prime Universe comic, through Donald Duck musing about his universe's version of the island that it would be a daft place to build a Money Bin.
