Jems are the primary currency of Tarsan. Because Tarsan has a tendency to be the baseline for most currencies, jems are used as the baseline currency which is used to compare against all other currencies.
Jems were officially established as the currency of the country on
date: 16.4.1072 TSC; tar. The original form were imprinted metal disks in 1j, 7j, and 49j quantities. The disks were gradually larger with the 1j being an inch across, the 7j at 1.5 inches, and the 49j at two inches.
Fractional jems, called chips (“c”) were imprinted metal bars that were 1/49th of a jem.
date: 22.6.1605 TSC; tar with an almost unanimous decision by the great families, Tarsan reissued jems in a new format, a purely paper format with various magical components and quantities that were easier to work with exchange.
The bills are all the same size at five inches by two inches with a brightly colored illustration. The material is sturdy with metal fibers woven into a dense paper.
The lowest seven denominations have a portrait of the current head of a great family on one side and a detailed illustration of the capital family town for that family.
The chips were retained as physical bars but they were reissued at tenth jem (0.1j) pieces.
There are a number of security features on the bills with more extensive ones for higher denominations.
One of the primary complaints about the currency is the fragility of the resonance-sensitive features. Outside of the cities, they are frequently triggered which makes those features useless.
At the moment, these are considered acceptable because reissues due to the triggered features lets the great families (in specific, Rinfir) control the amount of bills in circulation and therefore the value of the jem.
