1871 5C PR66 Cameo PCGS CAC. 1871 5C PR66 Cameo PCGS. CAC. The 1871 has few survivors that have the reflective surfaces needed to establish cameo contrast and frequently serves as high-grade alternatives to the conditionally rare circulation strikes. This attractive Premium Gem is a happy exception, with frosty design elements and mirrored fields that show accents of champagne-gold patina. Mintage 960.
