Guatemala
Charles III 8 Reales 1777 NG-P, Nueva Guatemala mint, KM36.2, AU Details (Surface Hairlines) NGC. Well struck and showing much detail but harshly cleaned long ago. Although this is perhaps the more available date (together with the 1787), the present example is still a decent type coin for this very scarce bust denomination issued at the NG mint between 1776 and 1787.
Estimate: 400-600 USD
