Republic 8 Reales 1828 Go-MR XF40 PCGS, Guanajuato mint, KM377.8, DP-Go08. A higher-end example of this rare date, partially lustrous and attractively and very scarce in this preservation: DP notes that "High grade examples are almost non-existent" and only 4 coins are currently certified higher by NGC (and one in the same grade).
Estimate: 300-400 USD
