1/4 Real Costa Rica

Costa Rica's Casa Nacional de Moneda in Cartago was operating under severe material constraints by the 1840s, and the quarter real represents the smallest denomination they were producing in silver at the time. The mint's output was chronically limited by the difficulty of sourcing consistent silver supplies in a newly independent Central American republic still untangling itself from the Federal Republic of Central America, which had dissolved in 1838.

KM#23 is known with die alignment irregularities common to the Cartago facility's hand-operated equipment.
