Once these coins entered the market, many of them were taken to money changers, such as gold shops or silver shops, and converted to senka (base metal coins) for use, as the precious metals were worth more than their money value.
この様な貨幣は市場に出ると当時としては余にも高額なものであったため、金屋および銀屋などの両替商に持ち込まれ、銭貨に替えて使用されることが多かった。
