The English pound sterling, in the time of Edward I. contained a pound, Tower weight, of silver of a known fineness.

在爱德华一世时代， 英镑包含一磅塔重的已知纯度的银。

In 1512, six shillings and eightpence contained only two ounces of silver, Tower weight, and were equal to about ten shillings of our present money.

1512 年，六先令八便士仅含两盎司白银（塔重），相当于我们现在的货币约十先令。
