Gold Double Eagles and Eagles were passed through the finishing rollers three times. Gold ingots varying in sizes and weights were received from the smelter and then broken down into oblong pieces of gold strips, by passing the metal through heavy rollers. The die was approved, then hardened and tempered ready to produce the coins. When the model of the coin was made it was placed on a lathe and reduced to the size desired for the coin. After the design of a gold coin was approved, the mint staff proceeded to prepare dies with a thick coating of transfer wax under pressure to transfer a penciled tracing. The melting departments used coal burning furnaces to smelt the raw gold and silver into 90% fine coinage.

It was our first president, George Washington, who directed the land for the US Philadelphia Mint to be purchased and constructed.

This act established the first national mint in the United States. On April 2, 1792, Congress passed the Coinage Act. Then in 1791, Alexander Hamilton endorsed the use in gold as our standard money. By 1785, the Grand Committee of the Continental Congress recommended Five Dollar Gold Pieces. Thomas Jefferson, as member of the House of Representatives, recommended a Dollar Unit of Exchange in 1782.
