An Inquiry into the Nature and Causes of the Wealth of Nations

by Adam Smith

It is the same case with the coin. Nobody imagines, I believe, that even the greater part of the annual coinage, amounting, for ten years together, before the late reformation of the gold coin, to upwards of £800,000 a-year in gold, was an annual addition to the money before current in the kingdom. In a country where the expense of the coinage is defrayed by the government, the value of the coin, even when it contains its full standard weight of gold and silver, can never be much greater than that of an equal quantity of those metals uncoined, because it requires only the trouble of going to the mint, and the delay, perhaps, of a few weeks, to procure for any quantity of uncoined gold and silver an equal quantity of those metals in coin; but in every country the greater part of the current coin is almost always more or less worn, or otherwise degenerated from its standard. In Great Britain it was, before the late reformation, a good deal so, the gold being more than two per cent., and the silver more than eight per cent. below its standard weight. But if forty-four guineas and a-half, containing their full standard weight, a pound weight of gold, could purchase very little more than a pound weight of uncoined gold; forty-four guineas and a-half, wanting a part of their weight, could not purchase a pound weight, and something was to be added, in order to make up the deficiency. The current price of gold bullion at market, therefore, instead of being the same with the mint price, or £46:14:6, was then about £47:14s., and sometimes about £48. When the greater part of the coin, however, was in this degenerate condition, forty four guineas and a-half, fresh from the mint, would purchase no more goods in the market than any other ordinary guineas; because, when they came into the coffers of the merchant, being confounded with other money, they could not afterwards be distinguished without more trouble than the difference was worth. Like other guineas, they were worth no more than £46:14:6. If thrown into the melting pot, however, they produced, without any sensible loss, a pound weight of standard gold, which could be sold at any time for between £47:14s. and £48, either in gold or silver, as fit for all the purposes of coin as that which had been melted down. There was an evident profit, therefore, in melting down new-coined money; and it was done so instantaneously, that no precaution of government could prevent it. The operations of the mint were, upon this account, somewhat like the web of Penelope; the work that was done in the day was undone in the night. The mint was employed, not so much in making daily additions to the coin, as in replacing the very best part of it, which was daily melted down.

Were the private people who carry their gold and silver to the mint to pay themselves for the coinage, it would add to the value of those metals, in the same manner as the fashion does to that of plate. Coined gold and silver would be more valuable than uncoined. The seignorage, if it was not exorbitant, would add to the bullion the whole value of the duty; because, the government having everywhere the exclusive privilege of coining, no coin can come to market cheaper than they think proper to afford it. If the duty was exorbitant, indeed, that is, if it was very much above the real value of the labour and expense requisite for coinage, false coiners, both at home and abroad, might be encouraged, by the great difference between the value of bullion and that of coin, to pour in so great a quantity of counterfeit money as might reduce the value of the government money. In France, however, though the seignorage is eight per cent., no sensible inconveniency of this kind is found to arise from it. The dangers to which a false coiner is everywhere exposed, if he lives in the country of which he counterfeits the coin, and to which his agents or correspondents are exposed, if he lives in a foreign country, are by far too great to be incurred for the sake of a profit of six or seven per cent.

The seignorage in France raises the value of the coin higher than in proportion to the quantity of pure gold which it contains. Thus, by the edict of January 1726, the mint price of fine gold of twenty-four carats was fixed at seven hundred and forty livres nine sous and one denier one-eleventh the mark of eight Paris ounces. {See Dictionnaire des Monnoies, tom. ii. article Seigneurage, p. 439, par 81. Abbot de Bazinghen, Conseiller-Commissaire en la Cour des Monnoies à Paris.} The gold coin of France, making an allowance for the remedy of the mint, contains twenty-one carats and three-fourths of fine gold, and two carats one-fourth of alloy. The mark of standard gold, therefore, is worth no more than about six hundred and seventy-one livres ten deniers. But in France this mark of standard gold is coined into thirty louis d’ors of twenty-four livres each, or into seven hundred and twenty livres. The coinage, therefore, increases the value of a mark of standard gold bullion, by the difference between six hundred and seventy-one livres ten deniers and seven hundred and twenty livres, or by forty-eight livres nineteen sous and two deniers.

A seignorage will, in many cases, take away altogether, and will in all cases diminish, the profit of melting down the new coin. This profit always arises from the difference between the quantity of bullion which the common currency ought to contain and that which it actually does contain. If this difference is less than the seignorage, there will be loss instead of profit. If it is equal to the seignorage, there will be neither profit nor loss. If it is greater than the seignorage, there will, indeed, be some profit, but less than if there was no seignorage. If, before the late reformation of the gold coin, for example, there had been a seignorage of five per cent. upon the coinage, there would have been a loss of three per cent. upon the melting down of the gold coin. If the seignorage had been two per cent., there would have been neither profit nor loss. If the seignorage had been one per cent., there would have been a profit but of one per cent. only, instead of two per cent. Wherever money is received by tale, therefore, and not by weight, a seignorage is the most effectual preventive of the melting down of the coin, and, for the same reason, of its exportation. It is the best and heaviest pieces that are commonly either melted down or exported, because it is upon such that the largest profits are made.

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 this case, 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, whatever the bank might lose by the seignorage, they would gain upon the price of the bullion; and whatever they might gain upon the price of the bullion, they would lose by the seignorage. They would neither lose nor gain, therefore, upon the whole transaction, and they would in this, as in all the foregoing cases, be exactly in the same situation as if there was no seignorage.

When the tax upon a commodity is so moderate as not to encourage smuggling, the merchant who deals in it, though he advances, does not properly pay the tax, as he gets it back in the price of the commodity. The tax is finally paid by the last purchaser or consumer. But money is a commodity, with regard to which every man is a merchant. Nobody buys it but in order to sell it again; and with regard to it there is, in ordinary cases, no last purchaser or consumer. When the tax upon coinage, therefore, is so moderate as not to encourage false coining, though every body advances the tax, nobody finally pays it; because every body gets it back in the advanced value of the coin.
