The Liberty Head, or Barber, dime was first struck for circulation in 1892 by the Philadelphia, New Orleans and the San Francisco mint. San Francisco minted less than a million, however, creating a key date, with one at G-4 worth $65, and reaching almost a thousand at the highest grades. In 1894, the San Francisco mint only minted 24 dimes, of which five were reserved for assay, and only nine are known today, creating the biggest key date in the Liberty Head series, where dimes are worth millions of dollars. In fact, one of these dimes at a grade of PF-66 went for $1,997,500 at a Heritage auction in January of 2016. There was a lot of fluctuation in the consistency of mintage at the New Orleans and San Francisco mints, creating a lot of key dates in the Liberty Head series, where various dimes in only G-4 are worth upwards of 50, some of hundreds of dollars. This leveled out after the turn of the century into the 1900s, where the most common G-4 value is $4, however there were still plenty of years where the San Francisco mint fell behind, creating key dates in 1901, 1903, 1904, and 1913. In 1907, there were four mints making dimes, with the first dime made at the Denver mint being struck. This lasted until 1909, where in 1909, the last dime was minted at the New Orleans mint. After ceasing the production of silver dollars, the main coinage struck at the New Orleans mint, the New Orleans mint stopped receiving funds after 1909, until it was finally decommissioned and closed indefinitely in 1911. All of its machinery was shipped to the Philadelphia mint, and the New Orleans mint was downgraded and became an assay office for the US treasury, before in 1932 the office was transformed into a federal prison for 12 years, until it was abandoned as a ‘storage facility’ for the coast guard. In 1978 it was restored, and is now a museum of American Coinage, the New Orleans Mardi Gras, the New Orleans Jazz Museum and displaying a collection of Newcomb pottery. After all of its years, it left its mark most on the Morgan Dollar, its most produced coin. After 1909 for the dime, it was only struck by the Denver, Philadelphia and San Francisco mints. In 1913 and 1915-16, the Denver mint did not make any dimes, therefore its last Liberty Head dime was struck in 1914. The Philadelphia and the San Francisco mint both struck Liberty Head dimes until the end of the series in 1916. There were 77 known different issues in the series.
