Costa Rica's coinage in the late 1920s was contracted almost entirely to foreign mints, and this issue was struck at the Waterloo & Sons mint in Birmingham — the same facility responsible for a significant portion of Central American bronze coinage during this period. The arrangement was purely economic; maintaining domestic mint infrastructure for low-denomination bronze was never cost-effective for small republics with limited circulation demand.
KM#170 had a relatively short type run, succeeded by design revisions tied to broader monetary reforms in the 1930s.
