The hostility of the Indian tribes along the routes was a problem for the Denver Mint because it made it difficult for the Denver Mint to accept gold and nuggets brought there by miners from the surrounding area. The gold and nuggets were accepted by the Assay Office for melting, assaying, and stamping of cast gold bars. The bars were then returned to the depositors as imparted bars stamped with the weight and fineness of the gold.
