Frederick I 4 Mark 1737-GZ MS64 NGC, Stockholm mint, KM387. Mintage: 17,000. An impressive survivor of this low-mintage issue, with a broad, lustrous planchet dappled lightly with russet tone on the reverse, and central designs that immediately awe the viewer. Rarely-offered at the Mint-State level, especially when borderline Gem, with few marks witnessed in the fields and an incredible portrait of the Swedish King.
Estimate: 2000-3000 USD
