Argor-Heraeus has refined gold in southern Switzerland since 1951, and its one ounce bars are among the most widely accepted small-format gold products in the market. Each holds one troy ounce of .9999 fine gold, carries a unique serial number, and ships sealed with a matching assay certificate. For buyers who want Swiss refining and instant recognition at resale, this is the standard.
Key Features:
- Purity & Weight: 999.9 fine gold, 1 troy ounce, 31.1 grams
- Metal: Gold, refined and minted by Argor-Heraeus SA in Switzerland
- Front: Argor-Heraeus roundel, country of origin, weight, fineness, serial number
- Back: Plain polished field with no stamping
The front face leads with the Argor-Heraeus roundel, a circular hallmark with the interlocking AH monogram at center ringed by ARGOR HERAEUS SA. Below it the bar reads Switzerland, then 1 ounce, then Fine Gold, then 999,9 on separate lines. A small rectangular MELTER ASSAYER hallmark follows, and the individual serial number sits at the bottom. Lettering is cut cleanly into a bright mirror-polished surface with a raised border and softly rounded corners.
The back is left completely blank, a smooth unbroken field of polished gold. Argor-Heraeus keeps all identification on a single face, which is common practice among Swiss refiners producing minted bars.
The company operates from Mendrisio, Switzerland, near the Italian border, and holds LBMA Good Delivery accreditation. It supplies blanks and finished products to mints and banks across Europe, and its refining standards are recognized by dealers and vaults worldwide without additional testing.
Each bar arrives sealed in its original Argor-Heraeus assay card. The front of the package is printed in black and yellow with the refiner’s name and the serial number repeated in a window at the bottom edge. The reverse of the card lists weight, fineness, and certified assayer, marked with the Swiss flag and the assayer’s signature. Serial numbers vary by bar. Leave the seal intact, since an unopened assay carries the strongest resale position.
You get Swiss-refined gold with verified purity, matched paperwork, and worldwide liquidity in the most tradable unit available. Order your Argor-Heraeus 1 oz gold bar today while sealed assay stock is available.

These Argor-Heraeus 1 oz Gold Bars are one type of gold I buy for my Gold-Backed IRA. All the Gold in my IRA has a serial number. A layer of security for me as I had the bullion depository not list one of my bars and I could tell them the serial number of the unaccounted bar. Good value.
