Sigismund III gold 5 Ducat 1623 MS64 NGC, Bromberg mint, 17.6g, KM45, Fr-78, Gum-1257, Kop-1426 (R8). Struck in the year after a truce was reached with the armies of Gustav II Adolf of Sweden in the Polish-Swedish sub-conflict of the Thirty Years' War, this extremely rare piece was meant to portray a Poland and its King at the height of power, although in truth the Poles were on the defensive generally in this period and struggled to maintain control in their territories in Lithuania and Estonia. The present offering, one of three known examples of the type, is bright with full luster and semi-reflective fields, particularly on the reverse. Few post-strike imperfections are immediately noticeable on this near-Gem, and light coppery-red tone has settled into portions of the protected fields. The strike was even and exacting, bringing forth a stunning level of detail and the substantial planchet absorbed all of the movement of metal without exhibiting any ghosting or obvious striking weakness. A stunning issue, both in terms of its preservation and its extreme rarity, this magnificent specimen is poised to see contentious bidding for its inclusion in what must inevitably be one of the finest cabinets of Polish rarities.
