1 Onza Pattern

The 1947 onza pattern was struck as Mexico explored the possibility of issuing a formal silver bullion trade coin — a project that would not reach circulation until the 1949 onza, itself a short-lived issue discontinued after just two years. This 1947 piece is among the earliest physical proposals in that process, produced in extremely limited numbers at the Mexico City mint for official review rather than distribution.

KM#Pn196 is one of several pattern variants documented from this period, differing in minor details from the ultimately adopted design.
