Medium gray toning. Scarce. NGC graded VF-20. Purchased by Private treaty from Mike Dunigan, The Dan Holmes Collection." Shown is a 1764 eight reales from the Guatemala mint, of a type issued 1760-71. All pillar coinage from Guatemala is scarce and many issues are rare. Gilboy notes this date as "R" or "rare". Unlike the other colonial mints, Guatemala seems to have issued more four reales than any other denomination. Gilboy marks the half, one and two reales as "rare" and the eight reales as "scarce" to "normal." None are marked as common. Guatemala issues are notably cruder than other mints.
