For example, it was '4 bun when selling, 8 bun when buying' which means when money changers sell Nanryo Nishu Gin silver coins they would give 4 ichibu gin coins per ryo (0.6%) to the buyers but when they were buying they charged 8 ichibu gin coins (1.2%) to the sellers of Nanryo Nishu Gin.
例えば「売上四分、買上八分」すなわち、両替商が南鐐二朱銀を売るとき買手に一両当り銀四分を与え、買上げるときは南鐐二朱銀の売り手から銀八分を徴収するよう取り決めた。
