"Sec. 18. And be it further enacted, That no coins, either gold, silver, or minor coinage, shall hereafter be issued from the mint other than those of the denominations, standards, and weights herein set forth."

Special attention was called to the dropping out of the silver dollar, both by Secretary Boutwell and Mr. Knox, and the opinion of experts was invited and given on this special matter and communicated to Congress. These sections, in the three years that the bill was pending in Congress, were changed either in the House or Senate in only one or two unimportant particulars.

Accompanying the report of Mr. Knox were the statements of Robert Patterson, of Philadelphia, confessedly one of the ablest scientists and metallists in the United States, in favor of dropping from our coinage the silver dollar. Dr. Linderman, the director of the mint, made the same recommendation. In the report accompanying the introduction of the bill, under date of April 25, 1870, Comptroller Knox gives the history of the silver dollar and the reasons for its discontinuance as follows:

"The dollar unit, as money of account, was established by the act of Congress April 2, 1792, and the same act provides for the coinage of a silver dollar, 'of the value of a Spanish milled or pillar dollar, as the same is now current.' The silver dollar was first coined in 1794, weighing 416 grains, of which 371¼ grains were pure silver, the fineness being 892.4. The act of January 18, 1837, reduces the standard weight to 412½ grains, but increases the fineness to 900, the quantity of pure silver remaining 371¼ grains as before, and at these rates it is still coined in limited amounts."

He then says:

"The coinage of the silver dollar piece, the history of which is here given, is discontinued in the proposed bill. It is, by existing law, the dollar unit, and assuming the value of gold to be fifteen and one-half times that of silver, being about the mean ratio for the past six years, is worth in gold a premium of about three per cent. (its value being 103.12) and intrinsically more than seven per cent. premium in our other silver coin, its value thus being 107.42. The present laws consequently authorize both a gold dollar unit and a silver dollar unit, differing from each other in intrinsic value. The present gold dollar piece is made the dollar unit in the proposed bill, and the silver dollar piece is discontinued. If, however, such a coin is authorized, it should be issued only as a commercial dollar, not as a standard unit of account, and of the exact value of the Mexican dollar, which is the favorite for circulation in China and Japan and other oriental countries.

"Note.—Assuming the value of gold to be fifteen and one-half times that of silver, the French 5-franc piece is worth about 96½ cents (96.4784); the standard Mexican dollar 104.90, our silver dollar piece 103.12, and two of our half-dollar pieces 96 cents."

The finance committee carefully examined the bill. We were not in any hurry about it. It was sent to us in April, 1870, and was printed and sent, by order of the Senate, to everyone who desired to read it or look over it.

That committee was composed of Messrs. Sherman, Williams, Cattell,
Morrill, Warner, Fenton and Bayard.

The bill was reported unanimously to the Senate December 19, 1870, after lying in the committee room for eight months.
