The term Guanin or Gua-NIN meaning (The Noble of Nobles) as a sign or rank of authority only used by the Caciques (Chiefs) and/or class of the Nitaino (Nobles) as a medallian carried around the neck.. It is a common misconception that pre-Columbian Americas lacked bronze and thus were not able to deploy hardened copper alloys. However, copper alloys are reported as ‘guanín’ by Columbus, a loan word borrowed from the Taino [1]  This misconception may well arise because tin, the common component of Eurasian bronze (although common in Bolivia), is rare in the Caribbean basin.
