Venezuela issued a series of gold coins around 1955 featuring native chiefs CACIQUES who fought the Spanish colonization. The nominal weights were 1.5, 6, 20 and 22 grams. Some were minted in Switzerland and a small amount in Caracas. Those from Caracas were less than the nominal weights. It wasn’t literal cheating because the coins were issued in terms of currency values. These coins were insurance against inflation as the currency depreciated rapidly in the following decades.
