Christian IX gold Proof 10 Kroner 1877 PR64 NGC, Copenhagen mint, KM790.1. Impressively mirrored in the fields with delicate frost on the raised surfaces and aside from a small as-struck lintmark just to the right of Christian's mouth, no marks to speak of. This example was last offered at auction in our Setember 2011 sale and brought $2,300.
Estimate: 1500-1800 USD
