| Reverse description | The reverse is an entirely blank, uniface field with no design, legend, or device of any kind, consistent with its classification as an obverse trial piece intended solely to test the obverse die. The plain field shows characteristic surface marks associated with a struck planchet, and the rim retains the milled collar impression. |

| Additional information |
Trial pieces for Cuba's 1968 coinage were produced as the revolutionary government was consolidating its monetary reforms following the 1961 currency conversion that wiped out the old peso system. Platinum was used for pattern and trial strikes not as a candidate circulation material but as a controlled test substrate — its consistent hardness and non-reactive surface made it useful for evaluating die quality and strike fidelity independent of the alloy variables present in base-metal blanks.
KM# Pn10 is among a small cluster of platinum trials from this year, none intended for circulation.
