Netherlands East Indies
Dutch Administration. Willem III Proof 1/20 Gulden 1854 PR64 Cameo NGC, KM303. Though the proof mintage is not known, the business strikes for this year had an output of just 1,000 pieces. Clearly, the former must be much lower, making this lustrous near-gem a rare and important piece. A similar example, an NGC PR62, realized a hammer of $1,000 in early 2017; the quality and eye-appeal of the present specimen is evident and will assuredly attract spirited bidding.
