A rare variety, rarer than the degree of rarity from Iger would indicate.
A Trojak with an early bust type (also known from 1595, Marzêta type 6), but with the date unseparated - placed between the Lewart coat of arms and the Daniel Koste mark. This date notation if it appears in the trade is mostly with the new portrait type (Marzêta type 10).
Beautiful state of preservation. Lots of natural luster. Very nice detail.
