500g Gold Bar: Price, Specs & Guide (2026)
A 500 gram gold bar contains 16.07537 troy ounces of gold. At a spot price of $4,059 per ounce (15 July 2026) that is a melt value of about $65,254 before any premium. The half-kilo bar is a deliberate middle ground: cheaper per gram than a 100g bar, and about half the outlay of a kilo. But it's a thinner niche than either, and it cannot be split — which is the honest trade-off this guide walks through.
How much is a 500g gold bar worth?
A 500g gold bar is worth roughly $65,254 at a gold spot price of $4,059 per troy ounce (15 July 2026). That's the melt value of its 16.07537 troy ounces of fine gold, before the dealer premium. Because gold trades around the clock, always confirm against a live price before you buy or sell.
| Gold spot (per oz) | 500g bar melt value |
|---|---|
| $3,800 | $61,086 |
| $4,000 | $64,301 |
| $4,059 (15 Jul 2026) | $65,254 |
| $4,200 | $67,517 |
| $4,500 | $72,339 |
How many troy ounces are in a 500g gold bar?
A 500g gold bar contains 16.07537 troy ounces of fine gold. The conversion is 500 ÷ 31.1035 grams per troy ounce. To value it at any moment, multiply 16.07537 by the current spot price per ounce — at $4,059/oz that comes to $65,254.
What are the specs of a 500g gold bar?
A 500g investment bar is 999.9 fine and holds 16.07537 troy ounces. At gold's density of 19.32 g/cm³ it occupies about 25.9 cm³ — surprisingly small and genuinely heavy in the hand. A Valcambi 500g cast bar measures roughly 85 × 40 × 8 mm, though cast bars are tapered and irregular, so treat dimensions as indicative rather than exact.
- Fine gold content: 500 g = 16.07537 troy oz
- Purity: 999.9
- Volume: ~25.9 cm³
- Typical cast bar size: ~85 × 40 × 8 mm (indicative)
500g vs 100g vs 1kg — which should you buy?
That last row is the point most guides skip. Five 100g bars hold the same metal as one 500g bar for a little more premium — but you can sell one at a time. A single 500g is all-or-nothing.
| 100g bar | 500g bar | 1kg bar | |
|---|---|---|---|
| Fine gold | 3.215 oz | 16.075 oz | 32.151 oz |
| Value at $4,059/oz | ~$13,051 | ~$65,254 | ~$130,508 |
| Typical premium | ~2–4% | ~1.5–3% | ~1–2% |
| Can sell in parts? | Yes (buy several) | No | No |
| Dealer liquidity | Very high | Thinner | High |
Why are most 500g gold bars cast rather than minted?
At 500 grams, cast bars dominate. Minted bars require rolling and stamping, which adds cost that makes little sense on a large, value-driven purchase — and a minted 500g carries a cosmetic premium that defeats the reason for buying the size. Cast bars are poured, hand-stamped, individually unique, and come with a certificate confirming authenticity and traceability.
Which refiners make 500g gold bars?
The 500g bars worth buying come from LBMA Good Delivery refiners: Argor-Heraeus, Valcambi, C. Hafner, Metalor and PAMP. All are 999.9 fine, so you're choosing on brand recognition and price rather than metal quality. Whichever you pick, buy it with its certificate and serial number intact — that's what makes resale quick and dispute-free.
- Argor-Heraeus — LBMA referee refiner, cast 500g
- Valcambi — hand-poured cast with certificate of authenticity and traceability
- C. Hafner — German refiner with a strong cast reputation
- Metalor — institutional-scale refiner, competitive premiums
