Collector insights
- Series context: Part of the Circulating commemorative coins series — collectors typically assemble full-year date runs, so single years within an established series carry demand beyond raw mintage.
- Struck at: Buenos Aires, Argentina (mintmark
BA). 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 113,826,499 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.
