Musan
The musan (Rokadong: musan), officially referred to as the gundarimusan (Rokadong: ), is the currency of the Kingdom of Rauratoshan.
Mechanics
The symbol used for musan ingame is "₻", though the symbol preferred is a Rokadong letter má () with two horizontal lines through it. The currency is backed primarily by raw iron, but distributed with written books. Raw gold and raw copper are also considered part of the kingdom's treasury. Current regulation by the Rauratoshan Office of the Treasury is that ₻1 is equal to 4 raw iron. Therefore, per the UŊMAO, ₻1 is equal to 18 raw copper (or 2 blocks thereof), and ₻3 is equal to 10 raw gold.
Musan can also be subdivided into 3 firos (, "shilling"), each worth 12 payang (, "penny"); that is, there are 36 (or 100 in seximal) payang to a musan. The number of payang in an account (beyond the integer number of musan in it) is traditionally represented in seximal, even though musan is typically represented in decimal. This is because this representation makes fractions of the musan more apparent, as "₻0.20" is more clearly one-third of a musan than "₻0.12".
Banks
The Royal Bank of Rauratoshan in Azeria manages the coffers of the Rauratoshan Kingdom, as well as conversions from diamond, raw copper, and raw iron into musan.
Other Rauratoshanian currency
The musan is the only state-backed form of currency in Rauratoshan. However, there are two other currency types that may see use in Rauratoshan, though neither are used for official business.
Furcoin
Furcoin (plural "furcoins") is an in-game cryptocurrency created as a joke.
A furcoin is a poisonous potato named "X X Furcoin", where X is a number. X can be any number, as long as it is less than or equal to the last number used. The first minted furcoin had a value of 1,0000,0000,0000. A furcoin can be "broken", or turned into multiple coins equal to the original coin's value, without affecting the ledger's current minimum value.
Furcoin is not simply represented as poisonous potatoes, it IS the potato. This allows anyone on the server to mint furcoin.
Like cryptocurrency, furcoins are ideally unregulated and decentralized. However, the requisite log to ensure that minted furcoins are less than or equal to the last furcoin used necessitates a "ledger" (though it is similar to a bank, it is NOT a bank, as it is called a ledger and has no staff) for furcoin, which is stored on a Google Sheets file.
Fake Diamonds
Fake diamonds are netherrack renamed to "Diamond". While technically non-renewable, fake diamonds are basically useless, so are not treated as a serious currency by Rauratoshan.
