In reality, during the continuance of any one regulated proportion between the respective values of the different metals in coin, the value of the most precious metal regulates the value of the whole coin. Twelve copper pence contain half a pound, avoirdupois, of copper, of not the best quality, which, before it is coined, is seldom worth sevenpence in silver. But as by the regulation twelve such pence are ordered to exchange for a shilling, they are in the market considered as worth a shilling, and a shilling can at any time be had for them. Even before the late reformation of the gold coin of Great Britain, the gold, that part of it at least which circulated in London and its neighborhood, was in general less degraded below its standard weight than the greater part of the silver. One-and-twenty worn and defaced shillings, however, were considered as equivalent to a guinea, which perhaps, indeed, was worn and defaced, too, but seldom so much so. The late regulations have brought the gold coin as near perhaps to its standard weight as it is possible to bring the current coin of any nation; and the order, to receive no gold at the public offices but by weight, is likely to preserve it so, as long as that order is enforced. The silver coin still continues in the same worn and degraded state as before the reformation of the gold coin. In the market, however, one-and-twenty shillings of this degraded silver coin are still considered as worth a guinea of this excellent gold coin.
The reformation of the gold coin has evidently raised the value of the silver coin which can be exchanged for it.
In the English mint a pound weight of gold is coined into forty-four guineas and a half, which, at one-and-twenty shillings the guinea, is equal to forty-six pounds
