Ron Guth: The 1848 Silver Dollar has the lowest mintage of any of the dates from the 1840s, bar none. The same can be said of the surviving population tabulated by PCGS; the 1848 has the lowest population of any date from the 1840s. It does not have the lowest population of Mint State examples, but it is not that far behind. On the high end, the 1848 is the only date found in MS66, where a single example has been certified by PCGS. Combined with the PCGS MS67 1849, these are the only two silver dollars higher than MS65 from that decade.
Most 1848 Silver Dollars show weakness on the 8th star and slight weakness on the 7th and the 9th through the 13th stars. On the reverse, the eagle usually shows strong details.
