An absolute equality of commercial value, free from disturbing fluctuations, is hardly attainable, and without it an unlimited legal tender for private transactions assigned to both metals would irresistibly tend to drive out of circulation the clearer coinage and disappoint the principal object proposed by the legislation in view. I apprehend, therefore, that the two conditions of a near approach to equality of commercial value between the gold and silver coinage of the same denomination and of a limitation of the amounts for which the silver coinage is to be a legal tender are essential to maintaining both in circulation. If these conditions can be successfully observed, the issue from the mint of silver dollars would afford material assistance to the community in the transition to redeemable paper money, and would facilitate the resumption of specie payment and its permanent establishment. Without these conditions I fear that only mischief and misfortune would flow from a coinage of silver dollars with the quality of unlimited legal tender, even in private transactions. Any expectation of temporary ease from an issue of silver coinage to pass as a legal tender at a rate materially above its commercial value is, I am persuaded, a delusion. Nor can I think that there is any substantial distinction between an original issue of silver dollars at a nominal value materially above their commercial value and the restoration of the silver dollar at a rate which once was, but has ceased to be, its commercial value. Certainly the issue of our gold coinage, reduced in weight materially below its legal-tender value, would not be any the less a present debasement of the coinage by reason of its equaling, or even exceeding, in weight a gold coinage which at some past time had been commercially equal to the legal-tender value assigned to the new issue. In recommending that the regulation of any silver coinage which may be authorized by Congress should observe these conditions of commercial value and limited legal tender, I am governed by the feeling that every possible increase should be given to the volume of metallic money which can be kept in circulation, and thereby every possible aid afforded to the people in the process of resuming specie payments. It is because of my firm conviction that a disregard of these conditions would frustrate the good results which are desired from the proposed coinage, and embarrass with new elements of confusion and uncertainty the business of the country, that I urge upon your attention these considerations. I respectfully recommend to Congress that in any legislation providing for a silver coinage and imparting to it the quality of legal tender there be impressed upon the measure a firm provision exempting the public debt heretofore issued and now outstanding from payment, either of principal or interest, in any coinage of less commercial value than the present gold coinage of the country.
