Established by an Act of Congress on April 21, 1862, the Denver Mint opened for business as an United States Assay office in 1863. Gold and silver nuggets were brought there by miners from the surrounding area for melting, assaying, and stamping of silver or gold cast bars. Today, the Denver Mint produces high quality collector commemorative coins, as well as currency. This Limited Edition train is chock full of U.S. Bureau endorsed currency which has been officially shred.
