Gold Bar

Gold Bars are items seen in a few Super Mario games.

Luigi's Mansion series
Gold Bars first appear in Luigi's Mansion. They account for 100,000G each and are often found in Treasure Chests.

Gold Bars return in Luigi's Mansion: Dark Moon, where they take the same role as they did in Luigi's Mansion. However, they are worth only 20G instead of 100,000G. They are also much more common and can appear after Luigi vacuums a ghost or flashes a gold spider, gold mouse, gold bat, gold beetle, or Gold Robomb with the Strobulb.

Gold Bars return in Luigi's Mansion 3, where they act as they did in Luigi's Mansion: Dark Moon.

Paper Mario series
Gold Bars are also used for storing money in Paper Mario: The Thousand-Year Door and Super Paper Mario. Mario cannot use them in combat in any way, and he can only sell them for coins. If Mario buys 100 items at a store, he can get a Gold Bar for free. If he buys 300 items, he can get a Gold Bar x3. In Paper Mario: The Thousand-Year Door, the Deepdown Depot sells Gold Bars for 110 coins, and they can be sold back for 100 coins.

In Super Paper Mario, Mario can give a Golden Leaf to Saffron to turn it into a Gold Bar and a Gold Bar into a Golden Meal, a useless item worth 50 coins (as opposed to the Gold Bar, which is worth up to 120 coins).
