Two types of currency systems have been defined thus far.
Metamor: Unit of currency is the mark, abbreviated M and divided into 100 cents. A mark has approximately the same value as a US dollar. Coins are issued for 1, 5, 10, and 25 cents and 1 and 2 marks; notes are printed in denominations of 5, 10, 20, 50 and 100 marks. A 5-cent coin is a quint, a 10-cent coin is a dek, and a 25-cent piece is a quarter-mark or simply quarter.
Quenardya: Unit of currency is the erin. It is abbreviated with an Elven letter that resembles a Y; people writing in Common script usually use the Y in its place. The erin is divided into 100 pence and has approximately the same value as a British pound. Coins are issued for the same denominations as marks, plus a 50-pence or half-erin piece. A 25-pence coin is called a celeb (pronounced with a hard "c"); the other coins do not have special names.
