Martian currency is typically divided into three oval coins. The pi a bronze coin equivalent one cent on earth, the teepi a silver coin worth about ten earth cents, and the tanpi a gold coin worth about a dollar. Nations seem to share this systems but the details of the specific coins seem to be noticeably different. Paper money is like a Earth check, it is redeemed twice a year. If a man issues more than he can redeem the government pays his creditors in full, then the man works off his debt in bondage, sometimes working in mines or on farms.
