Republic 8 Reales 1838 Mo-ML/M MS62 PCGS, KM377.10, DP-Mo21. Scarce as a date, typically struck, and truly rare as an example when considering that Mint State survivors of the date are few and far between and the overassayer is encountered with much less frequency than the normal assayer. Krause catalog price(s) for this item: $50 in VF, $80 in EF, $200 in UNC.
Estimate: 300-500 USD
