12 Sols Brûlé '1/2 Aidant or Gigot' - Ferdinand of Bavaria

Ferdinand of Bavaria became Prince-Bishop of Liège in 1612 through the direct intervention of his uncle, Duke Maximilian I, who leveraged Wittelsbach influence across the Rhineland ecclesiastical network. The copper coinage issued under Ferdinand — including this piece — was deeply unpopular. The "brûlé" designation, meaning burned or debased, reflects the public contempt for low-value copper issues that flooded Liège during a period of monetary disorder affecting much of the Spanish Netherlands and the surrounding principalities.

The "gigot" nickname, a colloquial term attached to this denomination by local users, stuck in the numismatic literature long after the coins left circulation.
