10 Euros - Jean-Paul Gaultier La Bretagne pêchée

Part of the Monnaie de Paris "Les Régions de France" series designed by Jean-Paul Gaultier, this issue was one of ten regional coins released in 2017, each reflecting a different French territory through Gaultier's distinctly personal aesthetic. The series was a deliberate commercial pivot toward collectible-themed issues, a strategy the Monnaie de Paris accelerated sharply after 2010 to offset declining demand for circulating coinage.

The .333 fineness places it at the lower threshold of what the French mint classifies as silver coinage — closer historically to medieval billon than to modern bullion.
