Ohio Precious Metals (OPM) is one of the United States’ largest refineries of precious metals. What originated in the garage of a couple bullion buffs in 1974 slowly grew into one of America’s most well-known refineries and one of the largest producers of COMEX and LBMA accredited bullion bars.
Currently, the 1oz OPM Gold Minted Bars are available to buy online from Gold Coast Bullion. |
