Bremen's archbishops held imperial minting rights confirmed by Frederick Barbarossa in 1186, and the thin, single-sided bracteate format dominant in northern Germany during this period reflects a deliberate regional preference rather than technical limitation — the style allowed higher-relief imagery from dies that would have cracked thicker planchets at this weight. At under half a gram, these were workhorse small change in a port economy already oriented toward the Hanseatic trade networks beginning to consolidate along the North Sea coast.
