William Petty,
Quantulumcunque concerning Money
“ Can it be imagined that the Goldsmith will give his Vessel weighing 20 Ounces of wrought, for 18 Ounces of unwrought Silver? For the Workmanship of Money is of little value. Now the Absurdity is the same in all other Commodities, though not so demonstrable as in a Commodity whose Materials is the same with Money. ”
