But if you have much of it , metal money is hard to carry around 但是你有太多时,金属货币不方便带在身上。
And then in the seventh century we had money in the form of precious metal 另外在七世纪时出现了贵重金属货币。
Because large sum of metal money is heaved and inconvenient to handle , government issue paper money 因为大量金属货币使用起来笨重不方便,政府便发行了纸币。
Afterward with the replacement of specie by banknotes whose issue was monopolized by the government authority , the seigniorage covered a large part of national revenue 以后随着纸币代替金属货币,而纸币的发行权由政府垄断,铸币税也就成了国家的一大收入。
At the late stage of metal currency times , however , finding out impure noble metal currency also could be in circulation corresponding with their par value , the coin minters thereupon adopted impure noble metals to mint coins . by this means the extra balance between par value and actual worth of currency was obtained and the seigniorage was produced accordingly 在金属货币时代后期,铸币者发现不足值、不足量的贵金属货币同样可以按其面额大小在市场上流通,于是他们采用没有十足成色和重量的贵金属来铸造货币,从而得到了货币面值大于实际价值的额外价差收入,铸币税也就产生了。
