10 oz Bunker Bullion Silver Bar

The 10 oz Bunker Bullion Silver Bar

This bar contains ten troy ounces (311.035 grams) of .999 fine silver. The 10 oz format is widely considered the most popular silver bar size because it balances low premiums with practical divisibility, and the biggest single premium drop on the silver bar scale happens between 1 oz and 10 oz, typically a 4 to 5 percentage point reduction. Under normal market conditions, 10 oz silver bars trade at roughly 4-8% over spot, compared with 8-15% for 1 oz bars.

Buying ten ounces in a single piece does mean accepting an all-or-nothing resale unit. Selling a 10 oz bar cannot be done in parts, so buyers who expect to liquidate in small increments sometimes mix this format with smaller pieces. For buyers accumulating $300-$500 or more at a time, dealer guidance commonly points to the 10 oz bar as the core recommendation.

Storage is a quiet advantage of the format. A typical 10 oz silver bar measures around 84mm x 49mm x 8mm, and ten ounces in one bar takes up less total space than ten 1 oz bars, which lose room to packaging and air gaps. Recognised-refiner silver bars command tighter buy-sell spreads on resale, and generic or lesser-known brands typically sell at melt value with no brand premium recovery, so the purchase premium paid up front matters more for bars like this one than for sovereign mint products.

10 oz Bunker Bullion Silver Bar Specifications

Silver bars at this weight are produced by one of two methods: cast bars are poured into moulds and have a more rustic finish at lower premiums, and minted bars are cut, stamped, and polished, often arriving sealed in packaging at slightly higher premiums. Cast production becomes more common at 10 oz and above. Typical dimensions for a 10 oz silver bar are approximately 84mm x 49mm x 8mm, compact relative to the value it holds.

At .999 purity the bar meets the standard fineness for retail silver bars. Most minted 10 oz bars ship in original sealed plastic, and sealed packaging aids resale; cast bars may ship loose. For verification, the usual checks apply: precise weight against the 311.035 g standard, dimension measurement, the magnet slide test (silver is diamagnetic), and specific gravity testing. Counterfeit silver bars exist, particularly in the 10 oz and 100 oz sizes, and the common approach is a copper, lead, or zinc core plated with silver, which a weight and dimension mismatch will reveal.

10 oz Silver Bar Tax Treatment by Country

Silver bars are taxed very differently from gold in most jurisdictions, and at .999 fineness this bar clears the investment-grade purity thresholds that matter in the exempt countries.

• UK: 20% VAT on purchase. Bars have no legal tender status, so gains are also subject to Capital Gains Tax. This double exposure makes silver bars the least tax-efficient silver form for UK buyers.
• US: No federal sales tax; state rules vary, and most states exempt bullion bars. Long-term gains are taxed at the collectibles rate of up to 28%. IRA-eligible silver must be at least 99.9% pure.
• Canada: 0% GST/HST, since the bar exceeds the 99.9% federal purity threshold.
• Australia: GST-free as investment-grade silver, which requires at least 99.9% purity.
• New Zealand: GST-exempt at 99.9% silver purity; no formal capital gains tax.
• Singapore: 0% GST under the Investment Precious Metals scheme (silver at 99.9% or finer); no capital gains tax.
• Hong Kong: no sales tax, no import duty, no capital gains tax.
• EU: full national VAT rates apply to new silver, typically 17-27% depending on the country.

10 oz Bars vs 1 oz Bars, Kilo Bars, and 10 oz Coins

Against 1 oz silver bars, the 10 oz format is the clear premium winner: roughly 4-8% over spot versus 8-15% for 1 oz pieces, the largest saving available from any single step up the weight scale. The 1 oz format keeps full flexibility for partial sales, which is the trade being made.

Against kilo bars (32.15 oz), the saving from going larger shrinks. Kilo bars run roughly 3-6% over spot, often less than one percentage point below 10 oz bars, while costing substantially more per piece and selling as an even larger all-or-nothing unit. Dealer commentary widely treats 10 oz as the better balance of premium savings and liquidity for most retail buyers. The same logic applies further up: 100 oz silver bars trade around 2-5% over spot but weigh about 3.1 kg each and are harder to sell in parts.

Against 10 oz silver coins such as the Royal Mint Valiant or 10 oz Queen's Beasts, bars are the cost-efficiency choice. Coins at this weight are uncommon and carry collector premiums above bar levels. Buyers maximising silver weight per dollar take the bar; buyers in the UK weighing CGT exposure should note that legal tender coins escape CGT where bars do not.
