Ron Guth: The mintage of the 1857 Three-Cent Silver is just over a million pieces, so it is usually priced the same as the more common 1858 (the most common date in the Type 2 series). However, there is little comparison between the two when their surviving populations are compared. According to the PCGS Population Report, the 1857 is more than twice as scarce as the 1858, not only in all grades, but in Mint State, as well.
Often, this date exhibits clashmarks (sometimes with indications of multiple die clashes), and both sides may show weakness on the outer peipheries.
The finest examples certified by PCGS are six at the MS66 level.
