The Canath is the currency of the Star Kingdom of Rigel.

It is one of the last physical currencies and takes the form of two discs of material, one within the other.

The coins themselves are quite plain with little to no ornamentation. They consist of a lithium-platinum alloy outer disc and an aetherium inner disc. Counterfeiting is discouraged via the use of a process exclusive to the Royal Treasury which controls both abundance and composition of elements and exact dimensions of each coin. Further, each series of coins (a new series is periodically minted when older coins are removed from circulation) features traits that are very difficult to find unless an analyst knows precisely what to look for.

Understandably, the production process of these coins is a closely guarded secret.
