Wilhelmina I gold Proof 10 Gulden 1926 PR67 NGC, KM162. Essentially flawless in presentation with rose-gold mirrors that seem to contain endless depth to their gloss and fully executed central designs that possess incredible highpoint definition. Noted as one of the great modern rarities among Netherland gold issues, produced with a surprisingly low figure of around 20 or so pieces, and likely among the finest survivors of the type.
