1858 - Present
July - Gold is discovered in Colorado (then part of Kansas Territory), beginning the Pikes Peak Gold Rush.
The city of Denver is founded four months later when miners and settlers flock to the area.
April 21 - Congress establishes a branch Mint in Denver exclusively for gold coinage. The government buys the building of Clark, Gruber & Company - a private mint located at 16th and Market Streets - for $25,000.
The Denver facility opens as an assay office. Miners bring their gold for melting, refining, assaying, and casting into bars.
The facility doesn't produce gold coins, as originally intended.
February 20 - Congress converts the assay office back into a branch Mint and authorizes Denver to produce gold and silver coins. However, coin production doesn't start until 1906.
The Denver Mint moves to a second building on West Colfax Avenue, where it's still located today. The building is modeled after the Medici-Riccardi Palace in Florence, Italy.
The government purchased the site in 1896 for $60,000 and construction began two years later.
February - The Denver Mint starts producing coins. By the end of the year, it produces 2,132,250 gold and silver coins, valued at $17.9 million.
December 18 - Gangsters steal $200,000 in five-dollar notes from a truck parked outside the Mint, in what is known as the "Great Mint Robbery." At the time, the Denver Mint stored paper money for the Federal Reserve.
