The Money Bin

The Money Bin is a three-cubic-acre building where Scrooge McDuck stores the portions of his money that he earned by himself. It was originally featured in the Uncle Scrooge comic book stories created by Carl Barks. It has also been featured in Scrooge's animated appearances, such as Scrooge McDuck and Money and DuckTales.

Origin
In-universe, the Money Bin was built in 1902, shortly after Scrooge entered the diamond market and could no longer sleep at night because all the money he was storing under his mattress raised his bed too close to the ceiling, necessitating a more suitable storage facility for his money. His favorite pastime is to dive off a springboard into his money and swim through it.

Although the money bin is a twelve-story skyscraper and vault (filled with three cubic acres of money), on various occasions it has been pulled around by a tractor, lifted to the top of a mountain, stolen by aliens from the bottom of the ocean, and blasted open with a cannon. The traditional location of the Money Bin is on top of Killmotor Hill. The money bin sits atop Futterman's Fault, a fault line which would prove catastrophic in the event of an earthquake.

The money bin is the victim of repeated assaults by Scrooge's enemies who try to steal his money, such as the Beagle Boys, who are after the bulk of Scrooge's money, and Magica De Spell, who is after Scrooge's "Number One Dime". To protect against these attempted break-ins, Scrooge has installed the greatest security system in the world to thwart any thought of even trying to intrude onto the premises.
