About Rocky Mountain Coin

Rocky Mountain Coin is a dealer of rare coins, currencies and precious metals in the heart of Denver, Colorado. Founded in 1976, we have grown to be one of the largest dealers in the United States−handling millions of dollars in coin, currency, and precious metal transactions each year.

We also buy and sell a variety of collectibles, gold jewelry, and pre-owned Rolex watches. In addition, Rocky Mountain Coin is one of Colorado’s premier dealers for Garrett, Minelab, and White’s metal detectors.

Our business philosophy has always operated on the principles of fair and honest dealings, proudly preserving a reputation for an exceptional quality of service, expertise and unmatched professional standards.
