In 1535 there was a radical change in the appearance of the bust of Sigismund I the Old and a different form of the legend on the coins was introduced. The king is definitely older on them.
This is a type of coin that is highly sought after and appreciated on the numismatic market.
Romanczyk has placed this variant under the number GGd1535_24 with the rarity RRR in the upcoming catalog, adding that Danzig pennies with this type of bust are quite rare.
