MEXICO. 50 Centavos, 1937-M. Mexico City Mint. PCGS MS-67+.
KM-447. The single finest known "top pop" on the PCGS population report, this satiny argent minor is immaculate. Contact marks cannot even be detected under magnification, and complex luster dominates so audaciously that one's attention is magnetically drawn to the coin's alluring surfaces.
Estimate: $115 - $160
