20 Mark - Wilhelm I Pattern

The German Empire's gold 20 Mark coinage was introduced under the currency unification of 1871–73, when Bismarck's government standardized the patchwork of state currencies into a single imperial system. This silver pattern — struck to the weight and dimensions of the gold production type but in .900 silver — was almost certainly a presentation or approval piece produced during the design finalization process, before the gold standard issue was confirmed for circulation.

Pattern pieces of this transitional moment are exceptionally rare; most were retained by mint officials or presented to state authorities rather than released.
