Infinite coin glitches

Infinite Coin Glitches are glitches that allow Mario to collect an endless supply of coins.

Cloning

Main article: Cloning

By grabbing an object as it unloads, Mario can load nearby coins to hold them instead. When he collects it, the clone does not update the coin spawner's flag and so does not count as collected, but still increments the coin counter.

Money Bag Duplication

Money bag duplication is a glitch which causes a money bag to duplicate itself into two money bags. By waking it up on the same frame it goes to sleep, you can cause it to create an awake one as well as an asleep one. Since these are technically separate objects, there are now two money bags. Money bag duplication can be used to get infinite coins in Snowman's Land.

• In the ABZ Challenge, extra moneybags are useful for some stars in Snowman's Land because you can bounce on them to get extra height.

Breaking-Disappearing Cork Box

Main article: Breaking-Disappearing Cork Box Glitch

The breaking-disappearing cork box glitch is caused by breaking a Cork box right when it disappears. This way it will respawn, but will also give three coins from breaking. The easiest way to do the glitch is to place the cork box on top of an object that becomes intangible when Mario moves away, and then returning to make the object tangible right when the box disappears.

This method of infinite coins does not take up object slots, and so it can be used to create more coins than cloning would. Infinite coins via cloning would eventually crash the game.

It is also possible to do this glitch while also grabbing the cork box fake by having the box break by touching the wall of a moving object.
