Fuchs Publique Deposited
A German slang or popular name for a red copper coin, and formerly frequently applied to the Pfennig. The word means a fox, and the allusion is of course to the color.
Gold Fuchs is used for a Ducat. Thus Langbein, Gedichte (ii. 137), has the lines:
"Statt der gehofften goldenen Fuchse, Fand man nur Kupfer in der Buchse."
