Abstract

1 はじめに : 本位貨幣においては、貨幣単位に含まれる素材価値の合計が貨幣価値を規定する。江戸期の三貨制度は特殊な複本位制である。公定相場と独立して通貨取引相場が存在し、それを前提として公定相場が定められた面がある。幕府当局は通貨供給や組成の変更によって取引に介入し、物価及び貨幣相場を誘導したとみることができる。……

There is no accurate way of knowing the prices of gold and silver bullion in the Edo period, as these prices were subject to bakufu (shogunate) regulation. However, it is possible to estimate bullion prices from the compositions of standard coins and data of the exchange rate in market, since currency transactions were conducted in exchange market under the Tokugawa coinage system as a unique triple monetary standard system. Gold coins were made of an alloy of gold and silver, while silver coins contained significant amounts of copper. Unlike gold and silver, copper bullion were on the market, and its price can be verified from the record. This enables us to estimate the prices of gold, silver, and copper bullion, also taking into consideration the market prices, i.e. exchange rate of gold and silver coins. The currency exchange ratio, which considers the value of all the materials, is determined by coin weight, material input coefficient, and bullion price. Solving this equation in reverse, we sought the bullion price. The results reveal a significant upward trend in the copper price, as well as a moderate upward trend in gold. The absolute values for gold and silver parity, however, did not diverge much from the international standard.
