10 Ducats - Aureus Magnus Port of Hamburg

This piece was struck by the Hamburg Senate to commemorate the 275th anniversary of the city's commodity exchange, the Hamburger Börse, one of the oldest in continental Europe. Hamburg's mercantile identity had survived Napoleonic annexation, the catastrophic fire of 1842, and two world wars — the port's commercial continuity was a point of genuine civic pride, and the issue reflects that rather than any federal monetary policy from Bonn.

The "Aureus Magnus" designation is a deliberate echo of Hamburg's medieval gold coinage tradition. At 35 grams of .980 fine gold, it was never intended for circulation — produced in limited quantities as a prestige bullion piece sold directly through the Hamburg city treasury.
