Ron Guth:
In 1872, employees at the San Fancisco Mint made 190,000 Dimes. All were struck by the same pair of dies, thus there is only one variety known for the year. Based on population and census reports, approximately two dozen Mint State examples are known, mostly in grades from MS63 to MS64. Gems are extremely rare and include only two at the PCGS MS65 level (one from the Eliasberg and Gardner collections, and one in the Simpson collection).
Most examples of this date are well-struck. If any weakness occurs, it is in the area left of the knot at the base of the wreath.
The price record for this date is $34,500.
