MEXICO. Mint Error -- Struck on Wrong Planchet -- 5 Pesos, 2009-Mo. Mexico City Mint. ANACS MS-65.
KM-907. Weight: 6.90 gms. Struck on a magnetic white-metal planchet, whereas the standard issue was struck on a bi-metallic aluminum-bronze planchet with a stainless steel ring. A nicely preserved example with some detail softness that presumably is the result metal being harder than was intended for the issue.
Estimate: $100.00- $300.00
