500g Gold Bar: Price, Premiums and Buying Guide

Price and premium in 2026

At $4,298 an ounce spot on 25 Sept 2026, a 500g bar's melt value is roughly $69,090. Our market range runs $70,500 to $73,000, a premium of about 2 to 4.5 percent, sitting between the 1kg bar's 1.5 to 4 percent and the 100g bar's wider band. That gap is arithmetic, not marketing: fixed minting and assay costs spread over less gold than a kilo bar carries, so the percentage premium creeps up. Spot moves every day, so this is a range, not a quote, we confirm the live number on WhatsApp before anything is agreed.

Refiner name, cast versus minted finish, and size all move the premium within that band. A Perth Mint or PAMP Suisse bar in mint condition with an intact assay card sits toward the top of the range, a plain cast bar from the same LBMA refiner sits toward the bottom.

Where it fits

This size suits a private client building a structured allocation rather than committing to a single kilo lump, and it fits the vault-storage minimums at bullion houses in all three hubs better than smaller bars do. In Singapore specifically, Le Freeport and The Reserve both operate bonded storage built around exactly this kind of mid-size, duty-and-GST-suspended holding.

999.9 fineness clears every purity threshold that matters here. Zero-rated at 5% UAE VAT under the investment-bullion rule, with B2B trade getting reverse-charge treatment under Cabinet Decision 127 of 2024. Exempt from Singapore's 9% GST as an Investment Precious Metal, since IPM only requires 99.5 percent purity on bars. Outside VAT and GST entirely in Hong Kong, where there is also no capital gains tax to plan around. A 1oz bar or a coin gets asked the same purity question, a bar at this fineness never fails it.

How to verify before you buy

Same discipline as any bar, just applied to a 500g piece rather than a kilo or a 100g retail bar.

A magnet test proves nothing on its own, tungsten-filled fakes exist precisely because tungsten's density sits close to gold's. Our full method is in how to verify a gold bar is real.

• Confirm the refiner sits on the current LBMA Good Delivery List.
• Match serial number, hallmark, fineness and year against the assay card.
• Check the serial on the refiner's own online portal, not just the paper certificate.
• Ask for an ultrasound or XRF scan if the seal has already been broken.
• Check the assay card and tamper-evident seal are intact.
• Buy only from a dealer the refiner has actually authorized.

We buy this size back too

Selling works the same way as buying, run in reverse. Assay first: XRF or ultrasound confirms fineness, we check the serial against the certificate if one exists, then quote against live spot. In Singapore that buyback market is genuinely uneven, payouts for the same bar reportedly vary 15 to 30 percent between buyers, exactly why an assay-first, comparison-quoted process matters more than the first number you are offered.

Send photos of the bar and its assay card on WhatsApp and we will give you a first-pass quote the same day, whichever direction you are trading.
