Extreme rarity. Mint Königsberg. On the obverse centrally in the field a royal sceptre, in a shield decorated with floral motifs, in the rim a legend, on the reverse a Prussian eagle, in the rim a legend and the date 1633. Kopicki lists only the 1625 groszy of George William with the bust of the ruler on the obverse, so this is not so much an unrecorded vintage as an UNREcorded TYPE. Minor sheet tip. Remnants of mint luster in the background.
