In 1873 Congress, anticipating the resumption of specie payments, made a general revision of the coinage laws in which the silver dollar was dropped from the list of authorized coins. This aroused no interest at the time, for under the ratio of 16 to 1 established in 1834 the silver dollar had become practically obsolete. In 1872 the silver bullion needed to coin a dollar was worth $1.02, so nobody thought of bringing it to the mint to be coined. Silver dollars, of which only about eight millions had been coined in the whole period since 1789, had not been in circulation for more than a generation. The act of 1873, which later came to be called by free silver advocates the "crime of '73," simply gave legal recognition to the fact that the silver dollar was no longer a part of the circulating medium.
