When looking at the price of an item in the book, first determine if more than 50% of that item is made of metal. If it is, the price listed stands. If it is not, then convert the price as follows: In place of gold, use ceramic. In place of silver, use bits. In place of copper, use beads.
Ceramic Piece: Approximately four inches in diameter, these flat discs are made from glazed clay baked hard and scored to easily break into 10 equal pieces. These pieces are called bits. The glaze used to make these coins is a closely guarded secret, with each kingdom using their own, very specific, recipe. This is done to prevent forgery, as making clay discs is very simple.
Bit: Literally, 1/10 part of a Ceramic Piece. Often times, the average person never sees an intact ceramic coin. Their existence consists of a handful of bits a week.
Beads (bds): Miniscule round glass beads. Often, these are kept on a string threaded through a hole in the center of each bead so as not to lose any. Many such strings are knotted every 10 to make counting easier.
