1871 Liberty Seated Half Dollar. WB-101. MS-63 (PCGS). Circulation strike half dollar production at the Philadelphia Mint surpassed one million coins in 1871 for the first time since the beginning of the Civil War. Even so, this Reconstruction era issue is scarce in the finer circulated grades and even more so in Mint State. Underrated compared to many later dates in the Liberty Seated series. From the Abigail Collection, Part II.
