Scientists have been waiting on technological advancements in order to confirm the date of the gold bar.
"The mexica pieces may have come from the treasure of Moctezuma's ancestors, which the Spaniards found in Teucalco or maybe among the spoils of war stored in royal warehouses in Petlaclaco, gun factories in Tlacochcalco or the crafts workshops in Totocalli," said Leonardo López Luján, an investigator with Mexico's National Institute of Anthropology and History.
He explained that researchers used fluorescent X-ray equipment to analyze the gold bar's chemical composition and match it with other historical pieces discovered in the same area.
