Denver Mint
There are currently four active mints, but only those in Philadelphia and Denver mint coins for general circulation, while the San Francisco Mint produces only silver and commemorative coins, and West Point produces gold, silver, and commemorative coins, and also stores gold and silver bullion (“Mint and Other Coin Production Facilities”).
The Denver Mint was officially established by an Act of Congress on 21 April 1862 as an Assay Office (to store and test the quality of gold and silver bullion). The Clark, Gruber & Company had been producing coins at their private mint at 16th and Market Street. In 1863, the federal government purchased their facilities and machinery for $25,000 (“United States Mint”). This location was allowed to manufacture coins for the United States as well as some foreign countries in 1874. It was not until 1895 that this branch officially became a part of the United States Mint (“United States Mint”).
The current building at West Colfax and Delaware Street initiated assaying operations in 1904. Construction began in 1897, but it did not commence production of coinage until 1906. Delays in the construction of these facilities often occurred because funding was inadequate, frequently addressed through requests by the secretary of the treasury for more capital, as late as 1904 asking a further $25,000, plus $14,500 for other expenses (The Creede Candle). Need for funds stemmed not only from the building itself, but from projected salaries of employees: $4,500 to the superintendent; $3,000 each for an assayer, a coiner, and a melter/refiner; $2,500 for a chief clerk; an assistant and two calculating clerks at $1,400 each; and $1,300 each for two clerks—laborers not included (The Creede Candle). The first superintendent was Frank L. Downer, formerly the assayer in charge of the Denver mint, who was promoted to the new position in 1904 (The Aspen Democrat).
Largely, the coinage operations were delayed due to the fact that Denver was awaiting delivery and installation of then state-of-the-art machinery that had been on display at the St. Louis Fair. Different types of presses were used for large or small coins, the former able to produce 90 coins per minute while the latter managed 120 in the same amount of time (The Daily Journal).
Before the new coinage presses were put to their intended use in producing money, the Denver mint was first used to produce a medal commemorating this momentous event, which was presented to the “state historical museum at the capitol” (Akron Pioneer). Even more curiously, the second reported work was a golden heart that was funded by “popular subscription,” or donations, which amounted to one penny per contribution for a grand total of 8,000 collected. This was a gift intended to honor President Roosevelt’s efforts to bring about peace between Japan and Russia and was presented to the President on 4 Monday, 1905 (Breckenridge Bulletin).
Intriguing Historical Tidbits
Once minting and assaying were truly phased out of the old mint buildings at 16th and Market, cleanup operations found among the refuse $30,000 worth of precious metals (The Daily Journal).
A thoroughly planned robbery by use of dynamite was foiled in December 1912 not by great police work, but because the would-be perpetrators foolishly left their written plans in the “public comfort station” of the post office (The Yuma Pioneer).
In 1920 it was discovered that a long-time employee had been secreting away gold in his prosthetic leg, then hid it in a hole in his cellar which he covered with concrete once full. Gold stolen after that was hidden under the walkway behind his home. The man, Orville Harrington, managed to steal $81,400 before he was caught (The Plateau Voice).
At 10:40 am on 18 December 1922, three gunmen ambushed a delivery wagon outside the U.S. Mint at Denver, stealing $200,000 dollars in $5 bills and fatally injuring bank guard Charles Linton, who passed that afternoon. Incredibly, not only the guards returned fire: employees rushed to arms stores and proceeded to aid in defending the mint (The Fort Collins Courier). Days later, the suspects evaded authorities near Greeley (The Daily Journal). The only man ever proven to be involved was J. C. Sloan, who was found dead in the getaway car the following month (Yampa Leader). By February, investigators turned up $80,000 of the stolen bills circulating the continental Northwest and linked it to an illicit clearing house in Minneapolis involving millions in thefts in the country throughout the previous year (The Daily Journal).
