Peru Tupac Amaru II 50 Soles - 1971

150th Anniversary of Independence. The coin also celebrates Tupac Amaru II who began the independence movement, which eventually lead to independence and was an inspiration to all of Latin America for independence from Spain. See the link below in order to get a history of these events and a numismatic legacy. This coin was not mentioned in the article, so I included her because the history is little known and important to South America. This one year type has a mintage of 100k.
