Republic 8 Reales 1852 Pi-MC MS62 PCGS, San Luis Potosi mint, KM377.12, DP-Pi31. A very pleasing example for this very scarce and underrated date, with shimmering luster as a result of pebbly fields and moderate tone that alternates between olive, brown and graphite shade. As mentioned by Dunigan and Parker, this date has become increasingly more scarce on a relative basis, as the number of known survivors for other dates has increased, while few new examples of this date have come to market in recent years.
Estimate: 400-600 USD
