1876 Liberty Seated Half Dollar. Proof-64 Cameo (PCGS). Dusted with golden-apricot and russet iridescence, lively surfaces reveal strong contrast between mirrored fields and satiny devices. This issues relatively high mintage of 1,150 Proofs was achieved in anticipation of increased sales during the United States centennial. Now, as then, examples are popular with collectors. From the Abigail Collection, Part II.
