The name Ryogae-cho found in various ginzas is due to the fact that cupellated silver from various silver mines in the country was purchased by each ginza with the officially minted chogin silver, and this trade was named Nangyo-gin silver exchange.
この各地銀座所在地の両替町という名称は諸国の銀山より産出される灰吹銀を、銀座が公鋳の丁銀を以って買い入れることを南鐐替（なんりょうがえ）と称したことによる。
