《明史·志·卷六十九》
如判杖刑六十下，苦役一年，全部赎钞是十二贯，除执行杖刑抵偿掉六贯，剩下的六贯折合银子七分五厘。其余类推。
如杖六十，徒一年，全赎钞应十二贯，除决杖准讫六贯，余钞六贯，折银七分五厘，馀仿此。
For example, if you were sentenced to 60 bastinado strokes and one year of hard labor, the total ransom in notes would be 12 guan, excluding 6 guan which would be offset by 60 strokes of bastinado. The remaining 6 guan would be converted into 7.5 fen of silver. The rest follows the same principle.
