The concave copper field shows the natural surface of the planchet as struck against an unworked die, exhibiting characteristic flow lines and surface marks consistent with a pattern or trial piece. No inscriptions, devices, or mint marks are present. |

Pattern coinage from the Casa de Moneda rarely surfaces with clean documentation, and this uniface copper strike is no exception. The 1945 date places it within a period of significant monetary deliberation in Mexico — the wartime economy had strained silver supplies, and the mint was actively testing alternative compositions and denominations before committing to production changes. Uniface patterns of this type were almost certainly struck for internal evaluation rather than formal presentation, which explains their near-total absence from contemporary records.
