如何翻译这句话?谢谢了

The intrinsic value of a coin is determined by the value of metal it is made of.

A money intrinsic value is by makes this money the metal value decision.

the inner value of a coin depends on the one of the metal that makes the coin.

比如说一枚金币和一枚铁币... 在它们流通使用的年代都给它们刻上十分... 在当时它们都只能买价格为十分的东西... 但到了现在社会... 金币的价值远超铁币... 一块金子当然比铁贵啦... 这就是内在价值的差别...
