GUATEMALA. Republic Bicentennial Gold Medal, 1976. NGC PROOF-64 Ultra Cameo. Weight: 27.84 gms. Obverse: Old city facade; Reverse: Guatemala City coat-of-arms. Struck to mark the 200th anniversary of the founding of Nueva Guatemala (Guatemala City) in 1776 after a massive earthquake in 1773 destroyed the old capital (Antigua Guatemala) and it was decided not to rebuild. Seemingly quite RARE as a type with few seen at auction. Ex: Richard Stuart Collection.
