Republic 8 Reales 1857 Pi-MC XF45 PCGS, San Luis Potosi mint, KM377.12, DP-Pi36. A moderately circulated example of this very rare date with reddish-gold toning accents that highlight both sides and a touch of granularity as a result of striking from fatigued dies. For accuracy's sake, a touch of PVC residue is noted over the surfaces and should be easily removable with the aid of acetone.
Estimate: 400-600 USD
