If in a country which wants and possesses a metallic currency of seventy millions of dollars, a paper currency to the same amount should be substituted, the seventy millions in gold and silver, being no longer wanted for that purpose, will be exported, and the returns may be converted into a productive capital, and add an equal amount to the wealth of the country.
In his Proposal for an Economic and Secure Currency Ricardo says:
A well regulated paper currency is so great an improvement in commerce, that I should greatly regret if prejudice should induce us to return to a system of less utility. The introduction of the precious metals for the purposes of money may with truth be considered as one or the most important steps toward the improvement of commerce and the arts of civilized life; but it is no less true, that with the advancement of knowledge and science, we discover that it would be another improvement to banish them again from the employment to which, during a less enlightened period, they had been so advantageously applied.
Mr. J. R. McCulloch, in commenting on the principles of money laid down by Ricardo, says:
He examined the circumstances which determine the value of money * * * and be showed that * * * its value will depend on the extent to which it may be issued compared with the demand. This is a principle of great importance; for, it shows that intrinsic worth is not necessary to a currency, and that provided the supply of paper notes, declared to be a legal tender, be sufficiently limited, their value may be maintained on a par with the value of gold, or raised to any higher level. If, therefore, it were practicable to devise a plan for preserving the value of paper on a level with that of gold, without making it convertible into coin at the pleasure of the holder, the heavy expense of a metallic currency would be saved.
It appears, therefore, that if there were perfect security that the power of issuing paper money would not be abused; that is, if there were perfect security for its being issued in such quantities, as to preserve its value relatively to the mass of circulating commodities nearly equal, the precious metals might be entirely dispensed with, not only as a circulating medium, but also as a standard to which to refer the value of paper.
In adopting a paper circulation—
Says Lord Overstone—
we must unavoidably depend for a maintenance of its due value upon the adoption of a strict and judicious rule for the regulation of its amount.
