| 背面描述 | The reverse is entirely blank, presenting a plain, unadorned field across the full diameter of the planchet. This absence of design is consistent with its classification as a reverse trial piece, struck solely to test the obverse die or planchet characteristics without committing to a finalized reverse design. The rim retains a slight raised edge from the collar. |

Cuba struck a small number of platinum trial pieces in 1968 as part of an internal review of coinage specifications under the Castro government's restructured monetary administration. These were never intended for circulation — they exist purely as metallurgical and die-testing artifacts, produced to evaluate strike pressure and surface definition against a non-standard planchet material. The reverse-only designation suggests the obverse die was either not yet approved or deliberately withheld from the trial striking.
