Reach into your pocket or change drawer and pull out a handful of U.S. pennies. Look carefully at their fronts—chances are most will have a small letter “D” just below the date. This is the mint mark for the Denver Mint, one of only a handful of facilities that produces U.S. currency. This particular location is a byproduct of the days when Denver was a gold-mining hub. When gold was found in Colorado in 1858, hundreds of merchants, miners and settlers moved in to claim their stake. A year later, Denver was founded, and several years after that, in 1863, the government decided to develop a mint facility here. In addition to producing money people use every day, the Denver Mint also stamps out a variety of not-in-circulation commemorative coins.
The grand architecture of the massive Renaissance-style 1904 mint building itself is worth checking out. To go inside, visitors must sign up for one of the free tours, which includes historical exhibits, vaults and gold bars.
