Denier Bracteate

Jena held minting rights sporadically through the medieval period, and this issue falls within a tense phase of Thuringian political fragmentation following the Saxon fratricidal conflict known as the Bruderkrieg, which formally erupted in 1446. Bracteate production in small Thuringian towns was already an anachronism by the mid-fifteenth century — most German mints had long abandoned the single-sided thin-flan technique — making Jena's continued use of it a function of local convention rather than any practical monetary logic.

The Pfennig Kabinett reference P.K.#585 places this squarely within a documented Thuringian bracteate sequence, though surviving examples in collectible condition are genuinely scarce given the fragility inherent to flans of this weight.
