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.

Their state-of-the-art facility in Jackson, Ohio employs over 200 employees today and has the capacity to refine a whopping 150 tonnes of gold, silver, platinum and palladium annually, sourced responsibly as per their Responsible Source Refinery Certification.


Currently, the 1oz OPM Gold Minted Bars are available to buy online from Cairns Bullion.

Bar Highlights:


  • Contains 1 troy ounce or 31.1g of 99.99% pure gold
  • Ships in CertiCard Security case
  • Serial numbered
  • Obverse features the large OPM logo, weight, purity, metal type, unique serial number and made in USA branding
  • Reverse design features a repeating angular pattern of the OPM logo

These investment grade minted bars are produced using state-of-the-art minting technology. The gold is first melted down into a liquid form, then machined into minted bar form.

The design of the 1oz OPM Gold Minted bars include the distinctive OPM branding. Underneath the logo is the metal type, weight and purity, along with a Made in USA stamp, a unique serial number and a QR code for metal provenance. The reverse of the bar features an angular repeating pattern of the OPM logo which gives the bars a distinctly raised look.

These 1oz bullion bars by OPM are available in silver and gold. Be sure to check out the full range of OPM products
