After the frenetic pace of production of Quarter Dollars in the previous two years, things settled down at the Philadelphia Mint in 1855. Mint employees produced nearly three million Quarters -- still a healthy amount, but more than a four-fold reduction from the previous year.
Most 1855 Quarters are well-struck, though some show occasional weakness on one or more of the obverse stars. High-grade examples are semi-scarce. Mint State examples cluster around the MS63 and MS64 grades but go as high as MS66 at POCGS. "Finest Known" honors could go to any one of the three PCGS MS66s, or the NGC MS67+* example from the Eric P. Newman collection that sold recently for a record $41,125.
