still continued to be somewhat above the mint price. Mr. Locke imputed this high price to the permission of exporting silver bullion, and to the prohibition of exporting silver coin. This permission of exporting, he said, rendered the demand for silver bullion greater than the demand for silver coin. But the number of people who want silver coin for the common uses of buying and selling at home, is surely much greater than that of those who want silver bullion either for the use of exportation or for any other use. There subsists at present a like permission of exporting gold bullion, and a like prohibition of exporting gold coin: and yet the price of gold bullion has fallen below the mint price. But in the English coin silver was then, in the same manner as now, under-rated in proportion to gold, and the gold coin (which at that time too was not supposed to require any reformation) regulated then, as well as now, the real value of the whole coin. As the reformation of the silver coin did not then reduce the price of silver bullion to the mint price, it is not very probable that a like reformation will do so now.
Were the silver coin brought back as near to its standard weight as the gold, a guinea, it is probable, would, according to the present proportion, exchange for more silver in coin than it would purchase in bullion. The silver coin containing its full standard weight, there would in this case be a profit in melting it down, in order, first, to sell the bullion for gold coin, and afterwards to exchange this gold coin for silver coin to be melted down in the same manner. Some alteration in the present proportion seems to be the only method of preventing this inconveniency.
The inconveniency perhaps would be less if silver was rated in the coin as much above its proper proportion to gold as it is at present rated below it; provided it was at the same time enacted that silver should not be a legal tender for more than the change of a guinea, in the same manner as copper is not a legal tender for more than the change of a shilling. No creditor could in this case be cheated in consequence of the high valuation of silver in coin; as no creditor can at present be cheated in consequence of the high valuation of copper. The bankers only would suffer by this regulation. When a run comes upon them they sometimes endeavour to gain time by paying in sixpences, and they would be precluded by this regulation from this discreditable method of evading immediate payment. They would be obliged in consequence to keep at all times in their coffers a greater quantity of cash than at present; and though this might no doubt be a considerable inconveniency to them, it would at the same time be a considerable security to their creditors.
Three pounds seventeen shillings and tenpence halfpenny (the mint price of gold) certainly does not contain, even in our present excellent gold coin, more than an ounce of standard gold, and it may be thought, therefore, should not purchase more standard bullion. But gold in coin is more convenient than gold in bullion, and though, in England, the coinage is free, yet the gold which is carried in bullion to the mint can seldom be returned in coin to the owner till after a delay of several weeks. In the present hurry of the mint, it could not be returned till after a delay of several months. This delay is equivalent to a small duty, and renders gold in coin somewhat more valuable than an equal quantity of gold in bullion. If in the English coin silver was rated according to it proper proportion to gold, the price of silver bullion would probably fall below the mint price even without any reformation of the silver coin; the value even of the present worn and defaced silver coin being regulated by the value of the excellent gold coin for which it can be changed.
A small seignorage or duty upon the coinage of both gold and silver would probably increase still more the superiority of those metals in coin above an equal quantity of either of them in bullion. The coinage would in this case increase the value of the metal coined in proportion to the extent of this small duty; for the same reason that the fashion increases the value of plate in proportion to the price of that fashion. The superiority of coin above bullion would prevent the melting down of the coin, and would discourage its exportation. If upon any public exigency it should become necessary to export the coin, the greater part of it would soon return again of its own accord. Abroad it could sell only for its weight in bullion. At home it would buy more than that weight. There would be a profit, therefore, in bringing it home again. In France a seignorage of about eight per cent is imposed upon the coinage, and the French coin, when exported, is said to return home again of its own accord.
The occasional fluctuations in the market price of gold and silver bullion arise from the same causes as the like fluctuations in that of all other commodities. The frequent loss of those metals from various accidents by sea and by land, the continual waste of them in gilding and plating, in lace and embroidery, in the wear and tear of coin, and in that of plate; require, in all countries which possess no mines of their own, a continual importation, in order to repair this loss and this waste. The merchant importers, like all other merchants, we may believe, endeavour, as well as they can, to suit their occasional importations to what, they judge, is likely to be the immediate demand. With all their attention, however, they sometimes overdo the business, and sometimes underdo it. When they import more bullion than is wanted, rather than incur the risk and trouble of exporting it again, they are sometimes willing to sell a part of it for something less than the ordinary or average price. When, on the other hand, they import less than is wanted, they get something more than this price. But when, under all those occasional fluctuations, the market price either of gold or silver bullion continues for several years together steadily and constantly, either more or less above, or more or less below the mint price, we may be assured that this steady and constant, either superiority or inferiority of price, is the effect of something in the state of the coin, which, at that time, renders a certain quantity of coin either of more value or of less value than the precise quantity of bullion which it ought to contain. The constancy and steadiness of the effect supposes a proportionable constancy and steadiness in the cause.
The money of any particular country is, at any particular time and place, more or less an accurate measure of value according as the current coin is more or less exactly agreeable to its standard, or contains more or less exactly the precise quantity of pure gold or pure silver which it ought to contain. If in England, for example, forty-four guineas and a half contained exactly a pound weight of standard gold, or eleven ounces of fine gold and one ounce of alloy, the gold coin of England would be as accurate a measure of the actual value of goods at any particular time and place as the nature of the thing would admit. But if, by rubbing and wearing, forty-four guineas and a half generally contain less than a pound weight of standard gold; the diminution, however, being greater in some pieces than in others; the measure of value comes to be liable to the same sort of uncertainty to which all other weights and measures are commonly exposed. As it rarely happens that these are exactly agreeable to their standard, the merchant adjusts the price of his goods, as well as he can, not to what those weights and measures ought to be, but to what, upon an average, he finds by experience they actually are. In consequence of a like disorder in the coin, the price of goods comes, in the same manner, to be adjusted, not to the quantity of pure gold or silver which the corn ought to contain, but to that which, upon an average, it is found by experience, it actually does contain.
By the money-price of goods, it is to be observed, I understand always the quantity of pure gold or silver for which they are sold, without any regard to the denomination of the coin. Six shillings and eightpence, for example, in the time of Edward I, I consider as the same money-price with a pound sterling in the present times; because it contained, as nearly as we can judge, the same quantity of pure silver.
Chapter 6 Of the component Parts of the Price of Commodities
In that early and rude state of society which precedes both the accumulation of stock and the appropriation of land, the proportion between the quantities of labour necessary for acquiring different objects seems to be the only circumstance which can afford any rule for exchanging them for one another. If among a nation of hunters, for example, it usually costs twice the labour to kill a beaver which it does to kill a deer, one beaver should naturally exchange for or be worth two deer. It is natural that what is usually the produce of two days' or two hours' labour, should be worth double of what is usually the produce of one day's or one hour's labour.
If the one species of labour should be more severe than the other, some allowance will naturally be made for this superior hardship; and the produce of one hour's labour in the one way may frequently exchange for that
