Cuba produced a small series of platinum trial strikes in 1969 to test die alignment and planchet behavior ahead of circulating coinage production — platinum's density and malleability made it occasionally useful for proofing work where precise metal flow data was needed. Whether this piece originated at the Casa de la Moneda or was struck under contract elsewhere remains unclear from surviving mint records.
