The United States have an interesting gold coin history spanning many decades. Each state comes with it's own identity and history, so the multitude of territorial gold produced is exceptional with many companies and mints producing similar but distinguishable gold coins. After the American War of Independence the US government (through the Coinage Act in 1792) established an independent monetary system using the dollar. It was commonplace in the states to come across or be paid in foreign gold coinage, but it wasn't until March 1849 that the US authorised the gold dollar coin to be minted.
