Edward Cooke, The Real Cause of the High Price of Gold Bullion (1819)
“ He is equally sensible of the folly of those arguers, who conceive that the Mint price and market price of gold must always be the same; because gold in coin and gold in bullion are of the same value and the same quality, and gold of any given alloy is always equal to the same quantity of gold of the same alloy. Surely it might strike these arguers that such reasonings upon the sameness of the value of gold are mere identical propositions: the same is the same: equals are equals: a quantity of gold of any given purity is equal to the same quantity of the same purity. ”
