Gold Bar

Gold Bars are first seen in Luigi's Mansion. They account for 100,000G each and are often found in treasure chests.

Bars also are used for storing money in Paper Mario: The Thousand Year Door. Mario cannot use them in combat in any way, and he can only sell them for coins. If Mario buys a lot of items at a store at once, he'll get a Gold Bar for free!

Single Gold Bars are worth 100 coins each, whereas Gold Bars x3 are worth 300 coins apiece.
