Los Altos (Quetzaltenango), Guatemala, 8 reales, sun-and-mountain countermark (Type I, 1838) on cross side of a Potosi, Bolivia, cob 8 reales Royal (galano), 1652 E post-transitional (Transitional Type VIII/B), 1-PH-6 at top, upside-down A for V's in PLV-SVL-TRA, dot above cross, unique combination, NGC AU details / holed. KM-77.10. Very important coin for both Guatemala countermark collectors and Potosi Royal collectors (not to mention 1652 transitional fans), as this is a unique combination, the Quetzaltenango countermark full and certain but mostly effaced by undercoin details, and the host from a heretofore unknown combination of dies (cross side matching Lazaro 113, pillars side missing in Lazaro but matching Mastalir VIII.1-B.ba.x[4]), also choice grade despite hole at top of pillars / near bottom of cross, contrastingly toned in crevices. NGC #6448950-007.
