5 Soldi ou cinquina - Federico Landi

Federico Landi acquired the Principality of Compiano — a tiny imperial fief in the Apennines above Parma — through inheritance in 1610, and promptly set about exploiting its minting rights with a thoroughness that alarmed his larger neighbors. The cinquina belongs to a brief coinage window in the early 1620s, when Landi issued across multiple denominations despite ruling a territory of negligible political weight. The Holy Roman Empire's tolerance for such pocket-state minting was already fraying by this period.

Billon issues from Compiano are rarely encountered in any grade, a direct consequence of the principality's tiny population and correspondingly small striking volumes.
