1 Friedrich d'Or - Frederick II Mule

A mule combining dies from different issues, this piece pairs incompatible obverse and reverse elements that were never intended to circulate together — most likely the result of a deliberate act at the Berlin or Königsberg mint, possibly to satisfy a collector or court order. Frederick II was an enthusiastic patron of the arts but exercised tight control over his mint operations, and unauthorized mule production carried serious consequences.

The 1749 date places this squarely in the Seven Years' War buildup period, when Prussian mint output was being closely monitored for military financing purposes.
