Willem I gold 10 Gulden 1840, Utrecht mint, KM56, Fr-327, MS64 NGC. A brilliant example, lightly toned over full, coruscating luster. The strike is sharp and the only marks noted are a couple on Willem's bust requiring a glass to see clearly. 1840 was the final year of issue for this type. Ex: Hammel Collection (Stack's 9/82, Lot 518).
Estimate: 1500-2000 USD
