Buy Platinum Bars — Compare Prices from Top Dealers

Platinum Bar Sizes

The 1 oz platinum bar is the standard for individual buyers — the most liquid size with the best balance of premium and portability. Gram-weight bars (1g, 5g, 10g, 20g) from Valcambi and PAMP offer a lower dollar entry point, though premiums per ounce are higher due to manufacturing costs. Larger bars — 10 oz and 1 kilo — carry the lowest premiums per ounce but require a larger capital commitment and may be harder to sell in partial quantities.

The Valcambi CombiBars solve the divisibility problem: a single bar scored into gram-weight segments that can be separated and sold individually. The 50-gram Platinum CombiBar, for example, contains fifty 1-gram bars in a single sealed assay package.

Why Platinum Bars Cost Less Than Coins

Platinum bars are produced by private refineries with lower overhead than sovereign mints — no die changes for annual designs, no legal tender certification, no limited-edition marketing. A 1 oz platinum bar from PAMP or Valcambi typically runs 3-5% over spot, compared to 5-8% for a 1 oz American Platinum Eagle. The platinum content and purity are functionally identical. The premium difference is branding and liquidity: coins are slightly easier to resell at tight spreads, bars are cheaper to acquire.

Platinum Refineries

Valcambi Suisse (Balerna, Switzerland) — One of Europe's largest precious metals refineries, operating since 1961. Produces the full range from 1 gram to 1 kilo platinum bars, plus the CombiBar series. LBMA-accredited.

PAMP Suisse (Castel San Pietro, Switzerland) — Accredited on the London Platinum and Palladium Market since 2003. Known for the Lady Fortuna design and the Multigram+25 series — twenty-five individually sealed 1-gram bars in a single package, designed for incremental selling.

Engelhard (historical) — No longer producing new bars, but Engelhard platinum bars remain actively traded on the secondary market. Engelhard pioneered the automotive catalytic converter, making them historically significant in the platinum industry. Secondary-market Engelhard bars sometimes carry collector premiums above melt value.

Argor-Heraeus (Mendrisio, Switzerland) — Refining since 1951, LBMA-accredited. Produces platinum bars from 1 gram to 1 kilo with a reputation for consistent quality and competitive pricing.

Heraeus (Hanau, Germany) — One of the world's largest precious metals processors. Heraeus platinum bars are widely available and trade at competitive premiums.

Supply and Pricing Context

Platinum's concentrated supply chain — roughly 70% of mine output comes from South Africa, with meaningful contributions from Russia and Zimbabwe — creates sharper price reactions to supply disruptions than gold or silver typically experience. That concentration shows up in premiums: during supply stress, platinum bar premiums widen faster than gold bar premiums because the refining pipeline is shorter and less diversified.
