Large earth coins are immense weapons formed through the use of earthbending and are often used as projectiles, thrown at opponents through the use of bending. Inspired by actual Earth Kingdomcurrency, the coins can be positioned side-by-side for a defensive, mobile wall or stacked to build a makeshift lookout tower. Skilled earthbenders can use these ten-foot diameter coins as a vehicle by riding in the three-foot wide hole at their centers.
These coins were used as a weapon again by an Earth Rumble VI contestant, The Big Bad Hippo. He swung one of the coins around in an attempt to knock down Toph, though she defeated the triple threat of The Big Bad Hippo, The Boulder, and the Headhunter by turning one of these large coins embedded in the floor of the arena with her earthbending, causing the Headhunter to collide with the other two competitors.
Several partially destroyed earth coins were littered around the outskirts of the plains village.
A small version of these coins, referred to as "earth disks", are used in pro-bending as the sole ammunition for earthbending contenders and are accessible via dispensers scattered throughout the arena floor. They were also employed by earthbending soldiers in the United Forces' navy as they attempted to destroy the squadron of Equalistbiplanes attacking the First Division.
