5 Lire Street Sweeper

San Marino's 1978 coinage series was issued as part of the republic's annual collector sets, which by the late 1970s had become a reliable revenue stream through international numismatic sales rather than domestic circulation. This particular issue belongs to a set themed around everyday working life — an unusually grounded subject choice for a microstate whose coinage was almost entirely collector-oriented by this period.

Aluminium 5 Lire pieces of this type saw virtually no street use.
