 silver was rated according to its 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 seigniorage 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 seigniorage 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
