1794 Liberty Cap Half Cent. C-7. Rarity-5+. High-Relief Head. EF Details--Environmental Damage (PCGS). Considerable sharpness throughout the design enhances the appeal of this scarce 1794 C-7 half cent. Dark brown surfaces are universally porous to explain the PCGS qualifier, but there are no sizeable or otherwise singularly mentionable blemishes. Manley Die State 2.0. From Heritages sale of the Mark Hays Collection of Half Cents, September 2019 Long Beach Signature Auction, lot 3008.
