San Marino issues coins through an annual mint agreement with the Italian state, and 1981 fell during a particularly prolific period of themed commemorative programming. KM#120 is part of a social-themed series the republic ran across multiple denominations that year, focused on the issue of food and agriculture — a subject chosen to align with broader FAO awareness campaigns that were drawing in small-nation coinages from across Europe and beyond.

Collector-only distribution kept circulation wear essentially nonexistent for virtually the entire mintage.
