Compare 100g Bullion Prices
Compare live prices on 100g bullion bars from trusted UK dealers. 100g is a widely traded bar weight that combines a manageable purchase price with substantially better premium efficiency than smaller bar formats — a popular choice for investors stepping up from coins or 1oz bars.
The 100g sweet spot
For many UK investors, 100g represents the point at which bar premiums begin to look genuinely attractive against coin alternatives. At roughly 3.215 troy ounces, a 100g bar holds materially more metal than three 1oz coins would, but typically at a meaningfully lower premium percentage. The trade-off is divisibility — bars cannot be part-sold the way coins can.
What's available
The main producer reaching UK investors at this weight is Metalor, with cast bars in both gold and silver. Cast bars carry a lower premium than minted bars of equivalent weight, reflecting the simpler production process.
UK tax position
Investment gold 100g bars meeting the 995 fineness threshold are VAT-exempt under HMRC rules. Silver 100g bars are subject to 20% VAT. Bars do not qualify for UK capital gains tax exemption — that benefit is reserved for UK legal tender coins. Investors weighing 100g bars against coins should factor CGT exposure into the comparison alongside premium savings.
