Collector insights
- Design heritage: Mario Baiardi is credited as the designer for the Circulating commemorative coins series. Designer attribution helps distinguish this issue from later restrikes or unofficial copies that reuse only the motif.
- Struck at: Buenos Aires, Argentina. Confirm the mintmark on your example before comparing prices — same-year issues from different mints often trade at very different levels.
- Mintage vs. survival: Reported mintage of 86,770,000 is high, but circulation attrition, currency-reform meltdowns, and low collector-preservation rates mean uncirculated (MS-63+) examples are meaningfully scarcer than the raw figure suggests. Check third-party population reports (PCGS/NGC) for realistic survival in top grades.
- Catalogue reference: Listed as
