1872 Octagonal 50 Cents. BG-938. Rarity-6-. Indian Head. MS-64 PL (PCGS). Splendid bright medium gold surfaces are nicely contrasted between reflective fields and frosty motifs. Well struck apart from a bit of softness through the central reverse. Nearly in the Gem category, this unique PL-designated example of the scarce BG-938 variety at PCGS is sure to have little difficulty finding its way into an advanced collection. This variety is attributed to maker Christopher (Christoph) Ferdinand Mohrig, and its numismatic discovery is credited to Robert H. Burnie sometime between 1952 and 1955.
