Frederik VII Proof 1/2 Rigsdaler 1854 PR64 NGC, Copenhagen mint, KM759. Fully reflective with little tone in the centers and a blend of mauve, blue and gold coloration at the edges. A scarcely seen denomination in the proof format, and considering the modest realizations we've observed on past sales, a coin that has been seemingly underappreciated by the market.
Estimate: 800-1200 USD
