Out of regret that Gomon gin silver coins had not circulated, it was Meiwa Nanryo Nishu Gin that was issued by some alterations, such as increasing the silver content and engraving 'Exchangeable to 1 ryo Koban with 8 of these' on it instead of a face value.
五匁銀が普及しなかった反省から、銀純度を上げる、額面の代わりに「8枚で小判1両に換える」と表記するなどの工夫がされ発行されたのが明和南鐐二朱銀（めいわなんりょうにしゅぎん）であった。
