100g Go Gold Bar

The 100g Go Gold Bar

This bar contains 100 grams of 999.9 fine gold, which works out at 3.2151 troy ounces, in one of the most premium-efficient formats in retail gold. The 100g weight class typically trades at 2-4% over spot, approaching kilo-bar territory, and the drop from 50g bars at 3-6% to 100g at 2-4% is one of the sharpest efficiency gains anywhere in the gram bar range. Only kilo bars offer meaningfully lower percentage premiums, and they demand a far larger outlay.

That positioning is the core of the buying decision. A 100g bar is a substantial purchase, currently in the region of $10,000-$10,500, so it suits buyers allocating serious capital who care more about gold per pound spent than about divisibility. Buyers who may want to liquidate in stages are better served by several smaller bars or by 1 oz gold bars, which carry slightly higher premiums but sell one at a time.

The 100g format is one of the most popular gold bar sizes in European markets, a standard trading size accepted by all major European dealers and most international ones, and it is also a common weight in Singapore and Hong Kong. In the US it is available but less dominant, since troy-ounce denominations come more naturally to that market. Physically, a 100g gold bar is compact, roughly 47mm x 27mm x 5mm depending on manufacturer, small enough to fit in a shirt pocket.

100g Go Gold Bar Specifications

The 999.9 fineness is the retail standard for gold bars and comfortably exceeds the 995 minimum that defines investment gold for VAT purposes in the UK and EU. Like all gold bars, this is refined gold in standardised form with no face value and no legal tender status; its value is purely its metal content.

One authentication note specific to this weight class: bars of 100g and up are where the tungsten-core counterfeiting risk becomes relevant, because tungsten's density of 19.25 g/cm3 sits close enough to gold's 19.32 that a plated bar can pass weight and dimension checks, and XRF surface testing only penetrates 10-50 microns. Ultrasonic testing is the most reliable non-destructive check, since gold and tungsten transmit sound at very different velocities. For retail buyers, the practical defence is simpler: buy from reputable dealers and keep the bar in its original sealed packaging, since breaking a seal can mean re-assaying at resale.

100g Gold Bar Tax Treatment by Country

At 999.9 fine, this bar qualifies as investment gold in every jurisdiction that defines the category, so purchase taxes are rarely an issue; the differences show up at disposal.

• UK: VAT-exempt as investment gold (995+ purity). Bars are NOT CGT-exempt, though: that exemption is reserved for UK legal tender coins like the Britannia and Sovereign. Gains above the £3,000 annual allowance are taxable at 18-24%, so for UK buyers expecting large gains, the bar's lower premium competes against the coin's CGT shield.
• EU: 0% VAT across all member states under the Investment Gold Directive for bars of 995+ fineness. In Germany, gains are tax-free after a 12-month holding period.
• US: No federal sales tax; roughly 35 states exempt bullion and several more exempt purchases above a threshold, which a 100g gold bar clears everywhere thresholds exist. Long-term gains are taxed at the collectibles rate of up to 28%. IRA eligibility requires 99.5%+ purity from an accredited refiner held at an approved depository.
• Canada, Australia, New Zealand: GST/HST-free or GST-free in all three, where exemptions cover gold at 99.5%+ purity in bar form.
• Singapore and Hong Kong: No purchase tax and no capital gains tax in either jurisdiction.

Go Gold 100g vs Valcambi, PAMP, and Smaller Bars

The 100g gold bar market is anchored by the big Swiss refiners. The Valcambi 100g is described as one of the world's best-selling products in this format, made by the largest precious metals refinery in the world by capacity at 2,000 metric tonnes a year, and it is the cost-focused buyer's benchmark. The PAMP Suisse 100g bar carries the Lady Fortuna design and a slightly higher premium, which it tends to retain better at resale. Argor-Heraeus, Heraeus, Umicore, Perth Mint, and the Royal Mint also produce 100g bars.

Brand recognition is the practical differentiator at this weight. LBMA-accredited refiner bars command better resale prices and universal dealer acceptance, while bars from less prominent producers are still liquid but can face wider spreads or assay requirements before a dealer will pay full value. Whatever the brand, a sealed bar in intact original packaging resells better than a loose one. Any premium saving on purchase should therefore be weighed against the exit: a cheaper bar that sells back at a deeper discount can cost more over the full cycle.

Down the weight scale, the 50g gold bar runs 3-6% over spot against 2-4% here, so consolidating into 100g is genuinely cheaper per gram. Up the scale, kilo bars shave the premium further but concentrate a very large sum in a single piece that must be sold all at once. For a five-figure allocation, 100g is the point where premium efficiency and manageable transaction size meet.
