10 Dollars - Elizabeth II The Black Cat from Zell

Part of a miniature gold series issued through the secondary collector market, this piece has no monetary circulation history whatsoever — it exists purely as a licensed collectible, struck to the absolute lower threshold of what modern minting equipment can handle at this diameter. Zell am Harmersbach in Baden-Württemberg has carried the black cat as its civic symbol since the medieval period, the legend tracing to a 13th-century tale of a miraculous cat surviving a tower fall and leading to the town's founding myth.
