Gold bars 1 oz
Number of products: 191 oz gold bars are the international standard with a mass of exactly 31.1035 g of fine gold 999.9 — one troy ounce, the unit used on all precious metals markets worldwide. It is the largest weight in the retail segment available without committing capital of 30,000–60,000 PLN as with 50 g or 100 g, at a premium of 3–6% — one of the lowest in retail and close to bullion coins.
At GoldInvest24 you will find the widest choice of 1 oz bars from LBMA refineries — Argor-Heraeus (incl. Kinebar), Valcambi (Green Gold), PAMP Suisse (Fortuna, Rosa), Perth Mint (minted and cast), Royal Mint, C.Hafner and the rare Istanbul Gold Refinery — plus collector editions and a "Various Producers" option from the secondary market (premium 2–4%). Check the variants as well as the current gold price and the terms of our precious metals buyback.
1 oz gold bar – the global bullion standard
The 1 oz gold bar is one of the few products with identical value in Tokyo, Zurich, New York and Warsaw. The troy ounce (oz t) comes from the weight system used by medieval merchants in Troyes (France) and was adopted by the London Bullion Market Association (LBMA) as the standard for trading precious metals. One troy ounce is exactly 31.1034768 g, commercially rounded to 31.1035 g.
The market values every ounce identically — whether from Switzerland's Valcambi, Australia's Perth Mint or Turkey's Istanbul Gold Refinery — provided it holds LBMA Good Delivery certification. It is this certificate that guarantees liquidity: a 1 oz bar will be bought by any dealer in the world at the spot price less only the buyback margin.
The 1 oz category holds a special place in the hierarchy of weights. It is the largest weight an average retail buyer can purchase without committing the 30,000–60,000 PLN needed for 50 g or 100 g. At the same time, the 3–6% premium is close to that of bullion coins.
LBMA producers in the 1 oz category
Argor-Heraeus (Mendrisio, Switzerland, 1951) offers minted bars, optionally as Kinebar with a counterfeit-proof hologram. Valcambi (Balerna, 1961) offers standard bars and the ethical Green Gold line. PAMP Suisse (1977) offers the iconic Fortuna, the premium Rosa series and collector series (Lunar, Good Luck Dragon).
Royal Mint (Wales, 886) offers the Britannia series and the collector Completer of the Queen's Beasts. Perth Mint (Australia, 1899) offers both minted and unique cast bars. C.Hafner (Pforzheim, 1850) and the rare Istanbul Gold Refinery (Turkey, LBMA since 2006) complete the range, along with the "Various Producers" option from the secondary market with the lowest premium (2–4%).

- Premium 3–6% — the lowest in retail.
- VAT exemption: bullion gold bars of fineness ≥ 995/1000 are VAT-exempt across the EU under Directive 2006/112/EC.

How much is a 1 oz gold bar worth?
The value of a 1 oz gold bar comes from the current gold price (1 oz × spot price) plus a premium of 3–6%. Collector variants sit at 7–14%, and the secondary market ("Various Producers") at 2–4%. Before buying, follow the current precious metals quotations.
Minted or cast?
Minted bars offer a mirror-smooth, precise surface (PAMP Fortuna, Kinebar). Cast bars (Perth Mint cast bar) have a rough, craftsman's surface — each piece is unique — at a slightly lower premium (3–5%). Gold content and the LBMA certificate are identical in both cases.
1 oz bar vs 1 oz coin
Both contain the same amount of fine gold. Standard bars carry a slightly lower premium (3–5%) than coins such as the Britannia or Kangaroo (4–7%); coins offer higher recognisability and an optional numismatic market. Compare the gold coins such as the Krugerrand.
VAT and tax matters
Products meeting the statutory definition of investment gold are exempt from VAT throughout the EU under Directive 2006/112/EC. In the case of a possible future resale, income tax matters should be assessed each time with regard to the individual situation.
