Pikmin (Series)

The Pikmin franchise features a small batch of coins, with all of them originating in Pikmin 2, and one of them going on to have a minor role in Pikmin 3.

Pokos
Pokos are the main currency used on the planet Hocotate (and presumably Koppai). Olimar and Louie are tasked with obtaining ten thousand Pokos to repay Hocotate Freight's debt at the beginning of Pikmin 2, and set off back to the planet PNF-404 to collect treasure to sell. When in caves, monster corpses can also be sold for a small amount of Pokos, instead of being used to produce more Pikmin like they are on the surface.

Pokos play a very minor role in Pikmin 3, appearing as the points system in the "Collect Treasure!" bonus stages, despite not being mentioned by name. They also have an updated design compared to their Pikmin 2 appearance, now looking a lot like a coin from the Mario series.

Pikmin 3 Deluxe features a new Side Stories mode where Pokos are mentioned and used quite similarly to the stages in the Wii U version. In this mode, Olimar and Louie are tasked with collecting more Pokos to save Hocotate Freight from yet another debt.

Treasures
Pikmin 2 also features some coins that can be found as treasures on PNF-404.

Lustrous Element
The Lustrous Element is found in the Hole of Heroes and is dropped by the Pileated Snagret after being defeated. It is tied with the four Titan Dweevil treasures as the 2nd most valuable treasure in the entire game, being worth one thousand Pokos. It is actually based on a golden dollar coin, a gold coin that was struck as a regular issue by the United States Bureau of the Mint from 1849 to 1889.

Mirrored Element
The Mirrored Element is found in the Dream Den. It is worth three hundred Pokos. It is based on the silver Morgan dollar coin, which was minted from 1878 to 1904, in 1921, and as a special non-circulating coin in 2021.

Unknown Merit
The Unknown Merit is found in the Bulblax Kingdom and is dropped by a Wollywog. It is worth one hundred Pokos. It is based on a wadōkaichin coin, the oldest official Japanese coinage, first minted on 29 August 708 on order of Empress Genmei.
