Support to that view may also be drawn from the last words of the clause giving congress the unrestricted power to regulate the value of foreign coin, as it would be difficult if not impossible to give full effect to the standard of value prescribed by the constitution, in times of fluctuation, if the circulating medium could be supplied by foreign coins not subject to any congressional regulation as to their value. Exclusive power to regulate the alloy and value of the coin struck by their own authority, or by the authority of the states, was vested in congress under the confederation, but the congress was prohibited from enacting any regulation as to the value of the coins unless nine states assented to the proposed regulation. Subject to the power of congress to pass such regulations it is unquestionably true that the states, under the confederation as well as the United States, possessed the power to coin money, but the constitution, when it was adopted, denied to the states all authority upon the subject, and also ordained that they should not make anything but gold and silver coin a tender in payment of debts. Beyond all doubt the framers of the constitution intended that the money unit of the United States, for measuring values, should be one dollar, as the word dollar in the plural form is employed in the body of the constitution, and also in the seventh amendment, recommended by congress at its first session after the constitution was adopted. Two years before that, to-wit, July 6, 1785, the congress of the confederation enacted that the money unit of the United States should "be one dollar," and one year later, to-wit, August 8, 1786, they established the standard for gold and silver, and also provided that the money of account of the United States should correspond with the coins established by law. On the 4th of March, 1789, congress first assembled under the constitution, and proceeded without unnecessary delay to enact such laws as were necessary to put the government in operation which the constitution had ordained and established. Ordinances had been passed during the confederation to organize the executive departments, and for the establishment of a mint, but the new constitution did not perpetuate any of those laws, and yet congress continued to legislate for a period of three years before any new law was passed prescribing the money unit or the money of account, either for "the public offices" or for the courts. Throughout that period it must have been understood that those matters were impliedly regulated by the constitution, as tariffs were enacted, tonnage duties imposed, laws passed for the collection of duties, the several executive departments created, and the judiciary of the United States organized and empowered to exercise full jurisdiction under the constitution.
