There are three standard types of coins used: gold koban, silver ichibuban, and bronze mon. There are 100 ichibuban to one koban. There are 10 mon to one ichibuban. Mon are made with a square hole in the center for stringing them together. Koban are only used for large trade transactions, and as currency between nobles. Most people only see ichibuban and mon in daily life.
All prices listed for equipment are in silver ichibuban unless noted with an (m) for bronze mon.
