3.5 oz MK Barz and Bullion Silver Bar

The 3.5 oz MK Barz and Bullion Silver Bar

This bar from MK Barz and Bullion contains 3.5 troy ounces of .999 fine silver. The weight is the first thing to understand about it: 3.5 oz is not one of the standard retail sizes. Common silver bar weights run 1 oz, 5 oz, 10 oz, 1 kg and 100 oz, so this bar occupies an in-between slot, heavier than the smallest everyday size but well short of the 5 oz step that most refiners produce next. Buyers who want a holding between those two standard points get exactly that here without buying multiple smaller bars.

The case for bars over coins applies in full. Silver bars carry the lowest premiums of any silver form, which makes them the most cost-efficient way to accumulate silver weight. A stacker whose priority is maximising ounces per dollar is better served by bar formats than by sovereign coins, and an odd-weight bar like this one still benefits from that structural advantage even though it sits outside the mainstream size ladder.

The trade-off is resale recognition. Bars from LBMA-accredited refiners command better resale prices than generic bars, and bars from lesser-known refiners will typically sell at melt value only, with no brand premium recovered. An unusual weight from a smaller producer is a buy-and-hold accumulation piece rather than a liquidity play; stackers who expect to sell in parts usually stick to standard sizes such as 10 oz silver bars, which dealers handle constantly and resell efficiently.

3.5 oz Silver Bar Specifications

The .999 fineness is the standard purity for silver bars; some sovereign producers such as the Royal Canadian Mint refine to .9999, but .999 is what the market treats as investment grade for bars. At 99.9 percent purity this bar clears the thresholds used in the tax rules of Canada, Australia, New Zealand and Singapore, which matters more for silver than the extra decimal place does.

At 108.86 g, the bar weighs a little under three and a half times a 1 oz bar and sits between the 1 oz and 5 oz rungs of the conventional size ladder. Verification follows the same methods as any silver bar: precise weight measurement, a dimension check, the magnet slide test (silver is diamagnetic) and specific gravity testing. Counterfeit silver bars are less common than counterfeit gold because silver carries less value per ounce, and the typical fakes, plated copper, lead or zinc cores, show up quickly under a weight and dimension check.

Tax Treatment of the 3.5 oz Silver Bar by Country

Silver bars get markedly worse tax treatment than gold in several major markets, and this bar follows the standard silver-bar rules everywhere.

• UK: 20% VAT on purchase. As a bar it has no legal tender status, so it is also liable to capital gains tax on disposal at 18% (basic rate) or 24% (higher rate), above the £3,000 annual allowance. VAT on entry plus CGT on exit makes bars the least tax-efficient silver format for UK investors.
• 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 eligibility for silver requires 99.9%+ purity from accredited refiners, so purity alone does not settle the question; check the refiner's accreditation status before assuming this bar qualifies.
• Canada: 0% GST/HST. Silver refined to at least 99.9% purity in bar form is federally exempt, and .999 clears that comfortably.
• Australia: 0% GST for investment-grade silver, defined as 99.9%+ purity in a form commonly traded on commodity markets.
• New Zealand: GST-exempt at 99.9%+ silver purity. No formal capital gains tax, though gains can be taxed as income if the bullion was acquired for resale.
• Singapore: 0% GST for silver of 99.9%+ purity in bar form under the Investment Precious Metals scheme.
• Hong Kong: no sales tax, no import duty and no capital gains tax.
• EU: silver bars attract the full national VAT rate, ranging from 17% to 27% depending on the member state. Margin schemes can reduce the effective rate on pre-owned bars in some countries, but new bars typically carry full VAT.

3.5 oz Bar vs the Standard Silver Bar Sizes

Because 3.5 oz is a non-standard weight, the practical comparison is against the standard sizes on either side of it. Published premium patterns for silver bars run roughly 8-15% over spot for 1 oz bars, 6-10% for 5 oz bars and 4-8% for 10 oz bars under normal market conditions, with the single biggest premium drop occurring between 1 oz and 10 oz. Larger bars buy silver weight more cheaply; smaller bars buy divisibility.

Against 1 oz silver bars, a single 3.5 oz bar trades away flexibility. Three and a half separate ounces can be sold one at a time; one 108.86 g bar cannot. The 1 oz format is liquid, though its per-unit handling cost is higher for dealers, which is part of why the smallest bars carry the steepest premiums.

Against 5 oz silver bars and 10 oz bars, the difference is recognition. The 10 oz bar is widely considered the most popular silver bar size, balancing low premiums with practical divisibility, and dealers resell both sizes efficiently. An odd weight from a smaller producer does not slot into that established market, and bars from lesser-known refiners typically resell at melt value only. Sealed bars in original packaging resell better than loose ones, which is worth bearing in mind for any bar held outside the standard sizes. The 3.5 oz format makes sense for a buyer who specifically wants that quantity in one piece; a buyer optimising for resale or for the lowest premium per ounce is usually better served further up the standard ladder.
