Some people argue that Mumon-ginsen coin was not 'a coin,' because it was practically exchanged based on the value of bare metal (In western Japan, silver Hyoryo kahei coins [currency valued by weight] such as mameitagin [an Edo-period coin] and Chogin [collective term of silver] were used even in the later Edo period.) 実際には地金価値で取引されたと考えられるため、「貨幣」と認めるべきか否かは議論がある(江戸時代など後代になっても、豆板銀や丁銀等の銀の秤量貨幣が、西日本では使用されている)。 |
