Christian IX Proof Krone 1875 PR66 Cameo NGC, Copenhagen mint, KM797.1. Nearly-pristine, this rarely-encountered Proof issue displays deeply-mirrored fields with just a hint of champagne color and frosty design elements that are expertly-struck. Incredibly scarce in this Gem designation, and currently the top certified example of this date in a Proof Cameo classification.
Estimate: 2000-2500 USD
