Lucca's medieval coinage operated under a peculiar legal fiction that persisted for centuries: the city struck coins in the name of the Holy Roman Emperor despite functioning as a fully self-governing commune. Charles IV formalized Lucca's imperial privileges in 1369, and this issue belongs to that arrangement — the emperor's name on a coin he never ordered, minted by a republic that jealously guarded its own autonomy. The billon popolino was the workhorse of local small commerce, circulating alongside heavier Florentine and Genoese issues in a market where fractional silver was perpetually scarce.
