Denier Bracteate

Hamburg struck these thin, single-sided bracteates during a period when the city was consolidating its commercial independence along the North Sea and Baltic trade routes. The bracteate format — a technique of pressing a single die through a flan so thin the image mirrors in relief on the reverse — was already archaic by the mid-fourteenth century in most German minting centers, making Hamburg's continued use of it notably conservative for a city otherwise aggressively modernizing its mercantile infrastructure.

At 0.28 g, the flan is exceptionally fragile. Undamaged survivors without splits or edge cracks are genuinely scarce.
