Power to coin money and regulate the value of domestic and foreign coin was vested in the national government to produce uniformity of value and to prevent the embarrassments of a perpetually fluctuating and variable currency.
Money, says the same commentator, is the universal medium or common standard by a comparison with which the value of all merchandise may be ascertained; and he also speaks of it as "a sign which represents the respective values of all other commodities." Such a power, that is the power to coin money, he adds, is one of the ordinary prerogatives of sovereignty, and is almost universally exercised in order to preserve a proper circulation of good coin, of a known value, in the home market.
Interests of such magnitude and pervading importance as those involved in providing for a uniform standard of value throughout the Union were manifestly entitled to the protection of the national authority, and in view of the evils experienced for the want of such a standard during the war of the revolution, when the country was inundated with floods of depreciated paper, the members of the convention who framed the constitution did not hesitate to confide the power to congress, not only to coin money and regulate the value thereof, but also the power to regulate the value of foreign coin, which was denied to the congress of the confederation.
Influenced by these considerations and others expressed in the opinion of the chief justice, this court decided in the case referred to, that the act of congress making the notes in question "lawful money and a legal tender in payment of debts" could not be vindicated as necessary and proper means for carrying into effect the power vested in congress to coin money and regulate the value thereof, or any other express power vested in congress under the constitution. Unless that case, therefore, is overruled, it is clear, in my judgment, that both the cases before the court are controlled by that decision. Controversies determined by the supreme court are finally and conclusively settled, as the decisions are numerous that the court cannot review and reverse their own judgments.
But where the parties are different, it is said the court, in a subsequent case, may overrule a former decision, and it must be admitted that the proposition, in a technical point of view, is correct. Such examples are to be found in the reported decisions of the court, but they are not numerous, and it seems clear that the number ought never to be increased, especially in a matter of so much importance, unless the error is plain and upon the clearest convictions of judicial duty.
Judgment was rendered for the plaintiff in that case on the 17th of September, 1864, in the highest court of the state, and on the 23d of June in the succeeding year the defendants sued out a writ of error, and removed the cause into this court for re-examination. Under the regular call of the docket, the case was first argued at the December term, 1867, but at the suggestion of the attorney general an order was passed that it be re-argued, and the case was accordingly continued for that purpose. Able counsel appeared at the next term, and it was again elaborately argued on both sides. Four or five other cases were also on the calendar, supposed at that time to involve the same constitutional questions, and those cases were also argued, bringing to the aid of the court an unusual array of counsel of great learning and eminent abilities. Investigation and deliberation followed, authorities were examined, and oft-repeated consultations among the justices ensued, and the case was held under advisement as long as necessary to the fullest examination by all the justices of the court, before the opinion of the court was delivered. By law, the supreme court at that time consisted of the chief justice and seven associate justices, the act of congress having provided that no vacancy in the office of associate justice should be filled until the number should be reduced to six. Five of the number, including the chief justice, concurred in the opinion in that case, and the judgment of the state court was affirmed, three of the associate justices dissenting. Since that time one of the justices who concurred in that opinion of the court has resigned, and congress having increased the number of associate justices to eight, the two cases before the court have been argued, and the result is that the opinion delivered in the former case is overruled, five justices concurring in the present opinion and four dissenting. Five justices concurred in the first opinion, and five have overruled it. Persuaded that the first opinion was right, for the reasons already assigned, it is not possible that I should concur in the second, even if it were true that no other reasons of any weight could be given in support of the judgment in the first case, and that the conclusion there reached must stand or fall without any other support. Many other reasons, however, may be invoked to fortify that conclusion, equally persuasive and convincing with those to which reference has been made.
All writers upon political economy agree that money is the universal standard of value, and the measure of exchange, foreign and domestic, and that the power to coin and regulate the value of money is an essential attribute of national sovereignty. Goods and chattels were directly bartered, one for another, when the division of labor was first introduced, but gold and silver were adopted to serve the purpose of exchange by the tacit concurrence of all nations at a very early period in the history of commercial transactions. Commodities of various kinds were used as money at different periods in different countries, but experience soon showed the commercial nations that gold and silver embodied the qualities desirable in money in a much greater degree than any other known commodity or substance. Daily experience shows the truth of that proposition, and supersedes the necessity of any remarks to enforce it, as all admit that a commodity to serve as a standard of value and a medium of exchange must be easily divisible into small portions; that it must admit of being kept for an indefinite period without deteriorating; that it must possess great value in small bulk, and be capable of being easily transported from place to place; that a given denomination in money should always be equal in weight and quality, or fineness, to other pieces of money of the same denomination, and that its value should be the same or as little subject to variation as possible. Such qualities, all agree, are united in a much greater degree in gold and silver than in any other known commodity, which was as well known to the members of the convention who framed the constitution as to any body of men since assembled, and intrusted to any extent with the public affairs. They not only knew that the money of the commercial world was gold and silver, but they also knew, from bitter experience, that paper promises, whether issued by the states or the United States, were utterly worthless as a standard of value for any practical purpose.
Evidence of the truth of these remarks, of the most convincing character is to be found in the published proceedings of that convention. Debate upon the subject first arose when an amendment was proposed to prohibit the states from emitting bills of credit or making anything but gold and silver coin a tender in payment of debts, and from the character of that debate, and the vote on the amendment, it became apparent that paper money had but few, if any friends in the convention. Article seven of the draft of the constitution as reported to the convention, contained the clause, "and emit bills on the credit of the United States," appended to the grant of power vested in congress to borrow money, and it was on the motion to strike out that clause that the principal discussion in respect to paper money took place. Mr. Madison inquired if it would not be sufficient to prohibit the making such bills a tender, as that would remove the temptation to emit them with unjust views. Promissory notes, he said, in that shape, that is when not a tender, "may in some emergencies be best." Some were willing to acquiesce in the modification suggested by Mr. Madison, but Mr. Morris, who submitted the motion, objected, insisting that if the motion prevailed there would still be room left for the notes of a responsible minister, which, as he said, "would do all the good without the mischief." Decided objections were advanced by Mr. Ellsworth, who said he thought the moment a favorable one "to shut and bar the door against paper money;" and others expressed their opposition to the clause in equally decisive language, even saying that they would sooner see the whole plan rejected than retain the three words, "and emit bills." Suffice it to say, without reproducing the discussion, that the motion prevailed—nine states to two—and the clause was stricken out and no attempt was ever made to restore it. Paper money, as legal tender, had few or no advocates in the convention, and it never had more than one open advocate throughout the period the constitution was under discussion, either in the convention which framed it, or in the conventions of the states where it was ratified. Virginia voted in the affirmative on the motion to strike out that clause, Mr. Madison being satisfied that if the motion prevailed it would not have the effect to disable the government from the use of treasury notes, and being himself in favor of cutting "off the pretext for a paper currency, and particularly for making the bills a tender, either for public or private debts." When the draft for the constitution was reported the clause prohibiting the states from making anything but gold and silver a tender in payment of debts contained an exception, "in case congress consented," but the convention struck out the exception and made the prohibition absolute, one of the members remarking that it was a favorable moment to crush out paper money, and all or nearly all of the convention seemed to concur in the sentiment.
Contemporaneous acts are certainly evidence of intention, and if so, it is difficult to see what more is needed to show that the members of that convention intended to withhold from the states, and from the United States, all power to make anything but gold and silver a standard of value, or a tender in payment of debts. Equally decisive proof to the same effect is found in the debates which subsequently occurred in the conventions of the several states, to which the constitution, as adopted, was submitted for ratification. Mr. Martin thought that the states ought not to be totally deprived of the right to emit bills of credit, but he says "that the convention was so smitten with the paper money dread that they insisted that the prohibition should be absolute."
Currency is a word much more comprehensive than the word money, as it may include bank bills and even bills of exchange as well as coins of gold and silver, but the word money, as employed in the grant of power under consideration, means the coins of gold and silver, fabricated and stamped as required by law, which, by virtue of their intrinsic value, as universally acknowledged, and their official origin, become the medium of exchange and the standard by which all other values are expressed and discharged. Support to the proposition that the word money, as employed in that clause, was intended to be used in the sense here supposed is also derived from the language employed in certain numbers of the Federalist, which, as is well known, were written and published during the period the question whether the states would ratify the constitution was pending in their several conventions. Such men as the writers of those essays never could have employed such language if they had entertained the remotest idea that congress possessed the power to make paper promises a legal tender.
