The Wealth of Nations_ Books 4-5 - Adam Smith [101]
The law for the encouragement of the coinage, by rendering it duty-free, was first enacted during the reign of Charles II. for a limited time; and afterwards continued, by different prolongations, till 1769, when it was rendered perpetual. The Bank of England, in order to replenish their coffers with money, are frequently obliged to carry bullion to the mint; and it was more for their interest, they probably imagined, that the coinage should be at the expense of the government than at their own. It was probably out of complaisance to this great company that the government agreed to render this law perpetual. Should the custom of weighing gold, however, come to be disused, as it is very likely to be on account of its inconveniency; should the gold coin of England come to be received by tale, as it was before the late recoinage, this great company may, perhaps, find that they have upon this, as upon some other occasions, mistaken their own interest not a little.
Before the late recoinage, when the gold currency of England was two per cent. below its standard weight, as there was no seignorage, it was two per cent. below the value of that quantity of standard gold bullion which it ought to have contained. When this great company, therefore, bought gold bullion in order to have it coined, they were obliged to pay for it two per cent. more than it was worth after the coinage. But if there had been a seignorage of two per cent. upon the coinage, the common gold currency, though two per cent. below its standard weight, would notwithstanding have been equal in value to the quantity of standard gold which it ought to have contained; the value of the fashion compensating in this case the diminution of the weight. They would indeed have had the seignorage to pay, which being two per cent., their loss upon the whole transaction would have been two per cent. exactly the same, but no greater than it actually was.
If the seignorage had been five per cent., and the gold currency only two per cent. below its standard weight, the bank would in thiscase have gained three per cent. upon the price of the bullion; but as they would have had a seignorage of five per cent. to pay upon the coinage, their loss upon the whole transaction would, in the same manner, have been exactly two per cent.
If the seignorage had been only one per cent. and the gold currency two per cent. below its standard weight, the bank would in this case have lost only one per cent. upon the price of the bullion; but as they would likewise have had a seignorage of one per cent. to pay, their loss upon the whole transaction would have been exactly two per cent. in the same manner as in all other cases.
If there was a reasonable seignorage, while at the same time the coin contained its full standard weight, as it has done very nearly since the late recoinage,
