The Imperial mark (known also as the Reydovan mark) (IM or RM) is the standard currency of the Reydovan Empire; it is equivalent to five Federation credits in the standard exchange rate. It comes in coin or credit-chit form, and can also be spent electronically via accounts in Imperial banks. It is legal tender in the Reydovan Empire and in the United Federation of Planets. The coin form of the mark only comes in the one-mark value, while the credit-chit form of the Imperial mark comes in increments of 1, 5, 10, 25, 100, 500, and 1000. One mark is divided into 100 mark-cents, in coin increments of 1, 5, 10, 25, and 50, much like the United States dollar.
