| Although the standard ryome for Ko Nanryo Nishu Gin was originally 10.12g, it was allowed to excess the weight by up to 0.18g for the convenience of the Ginza business at their expense and there were many weighing 10.30g. |
尚、古南鐐二朱銀の規定量目は本来二匁七分（10.12グラム）であるが、銀座における作業の都合などから五厘の過目（すぎめ）までは認められ過目分は銀座の負担とし、二匁七分五厘（10.30グラム）程度のものも少なくない。 |
