1 Ecu - Honoré II

Honoré II secured formal recognition of Monégasque sovereignty from Louis XIV in 1641 under the Treaty of Péronne, abandoning a century of Spanish protection in exchange for French backing — and it was this newly legitimized authority that made issuing coinage in his own name politically viable. The écu series followed directly from that diplomatic realignment.

KM#14 is among the larger silver issues of the principality and among the earliest to circulate under unambiguous Grimaldi sovereignty. Surviving examples in any condition above heavily worn are genuinely scarce; Monaco struck no coin in quantity and these saw real use.
