100oz Silver Bar

A 100oz silver bar holds 100 troy ounces of fine silver, which is 3,110.35 g or just over 3.1 kg of metal in one piece. It is the largest bar most UK private buyers ever take delivery of, and it is the size people pick when they want a lot of silver for the smallest dealer margin per ounce. The table above compares live offers from UK dealers that sell this bar.

Key facts about the 100oz silver bar

• Weight: 100 troy ounces (3,110.35 g) of silver.
• Purity: .999 fine silver, the usual standard for investment bars in the UK.
• Type: usually a cast bar, poured into a mould, with the refiner’s stamp, weight and fineness on the top face.
• Brands: the dealers in the table may ship different refiners. The listing is for a standard 100oz bar, not a specific brand.

Who buys a 100oz silver bar?

This bar suits buyers who already know they want a large silver position and plan to hold it for years. Typical reasons:

• You want the lowest premium over spot per ounce you can get on physical silver.
• You are happy to store one heavy item instead of a tube of coins.
• You do not expect to sell part of the holding. A single bar has to be sold in one go.

Is that you? If you think you may need to sell in small steps, a mix of smaller bars or coins gives you more room.

What to check before you buy

• Premium over spot. Compare the dealer price with the silver price per gram. On a bar this size, a small difference in premium adds up to a real sum.
• Delivery and insurance. A 3.1 kg parcel needs insured, signed-for delivery. Check whether the dealer includes it or charges it on top.
• Buy-back terms. Ask what the dealer pays when you sell back, and whether they buy bars from other refiners.
• Authenticity. Buy from known dealers, keep the invoice and check the stamp, weight and size. Our guide on how to spot fakes covers the basic tests.
• Storage. At home you need a safe and a note to your insurer. Many dealers also offer vault storage.

VAT and Capital Gains Tax on silver bars in the UK

Silver is not treated like investment gold in the UK. What does that mean for you?

• VAT: silver bars delivered in the UK carry VAT at the standard rate of 20%. Some dealers offer VAT free purchase only while the bar stays in a bonded or overseas vault.
• Capital Gains Tax: silver bars are not legal tender, so a gain on sale can be subject to CGT above your annual allowance. Read more in our page on capital gains tax on gold, where the same rules for bars apply.

UK legal tender silver coins such as the 1 oz Britannia silver coin are exempt from CGT, but they also carry VAT. That trade off is the main reason some buyers pick Britannias over bars.

100oz bar or smaller sizes?

• 100oz bar: lowest margin per ounce, one item to store, sold only as a whole.
• 1kg or 500g bars: a bit more per ounce, easier to split a holding.
• 1 oz coins: highest margin per ounce, easiest to sell in small parts, CGT free if they are UK legal tender.
