100 oz SilverTowne Silver Bar

The 100 oz SilverTowne Bar: Bulk Silver at Minimum Premium

The 100 oz SilverTowne silver bar contains 100 troy ounces (roughly 3.11 kg) of .999 fine silver. SilverTowne is a long-established US private mint whose generic bars are a staple of the North American stacking market, and the 100 oz format is the size that market was built around: the troy-ounce weight is a standard unit of trade in North American silver dealing, and every major bullion dealer buys and sells these bars.

The case for the size is arithmetic. Manufacturing, assaying, and packaging costs are fixed per bar, so spreading them across 100 ounces produces the lowest per-ounce premium of any standard retail silver bar. Small bars and especially government coins cost several percentage points more per ounce for the same metal. For accumulators building positions of 500 oz and up, those savings compound into real money.

The trade-offs are indivisibility and weight. A 100 oz bar can only be sold whole, to one buyer, where the same silver in 10 oz bars or 1 oz coins can be parcelled out. At nearly 7 lbs per bar, stacking multiples adds up fast. And most dealers will weigh, measure, or assay a secondary-market 100 oz bar before buying it, an extra step coins with known specifications avoid. This is a bar for committed stackers, not first purchases.

100 oz SilverTowne Bar Specifications

.999 is the standard fineness at this weight; the Royal Canadian Mint is the notable producer that goes to .9999. The 100 oz footprint is comparable to a large smartphone, just far heavier, and the rectangular form stacks by design.

Authentication deserves attention at this size because 100 oz bars are among the formats counterfeiters target. The good news is that silver fakes are detectable with basic tools: silver is diamagnetic, so a magnet slide test exposes plated cores, and precise weight and dimension checks catch copper, lead, or zinc substitutes. There is no tungsten problem as with gold, since tungsten is nearly twice silver's density (19.25 vs 10.49 g/cm3) and would be obviously overweight at correct dimensions. Buying from reputable dealers and keeping any original packaging intact protects resale value.

Tax Treatment of 100 oz Silver Bars by Country

At 100 oz the absolute tax numbers get large, so jurisdiction matters more than at smaller sizes.

• US: the primary market for this format. No federal sales tax; most states exempt bullion, others tax it or set thresholds (which a 100 oz bar will typically exceed where exemptions are threshold-based). Long-term gains are taxed at the collectibles rate of up to 28%. Bars are IRA-eligible at .999+ fineness when produced by accredited or ISO 9001 certified manufacturers.
• Canada: GST/HST exempt, as .999 silver in bar form clears the 99.9% federal purity requirement.
• UK: 20% VAT on purchase unless held in bonded storage, and bars have no CGT exemption, a double burden that is painful on a purchase this size. The UK and Europe also generally prefer kilo bars over the 100 oz format.
• EU: full standard VAT at national rates on new silver bars.
• Australia: GST-free at 99.9%+ purity, though kilo bars are the more common large format there.
• New Zealand: GST-exempt at 99.9%+ silver purity.
• Singapore: 0% GST for qualifying 99.9%+ silver bars; no capital gains tax.
• Hong Kong: no sales tax, duties, or capital gains tax.

SilverTowne 100 oz vs Branded Bars and Smaller Sizes

Within the 100 oz class, the choice is brand tier. Royal Canadian Mint bars offer .9999 purity, serial numbers, and LBMA Good Delivery status; discontinued Johnson Matthey and Engelhard bars trade with collector premiums on the secondary market; Asahi continues Johnson Matthey's refining lineage in current production. LBMA-accredited bars command tighter buyback spreads. SilverTowne sits in the generic tier alongside names like Sunshine Minting: typically cheaper to buy, with somewhat wider buyback discounts than the accredited brands. For pure cost-per-ounce stacking, that trade often favours the generic; for maximum resale flexibility, the branded bar wins.

Down the weight scale, the 10 oz bar is the popular compromise: most of the premium saving with far better divisibility, since selling silver in 10 oz increments is much easier than finding one buyer for 100 oz. The marginal premium saving from 10 oz up to 100 oz is smaller than the saving from 1 oz up to 10 oz, so the case for going all the way to 100 oz rests on buying in volume.

Against 1 oz silver coins, the comparison is stark: coins carry the highest per-ounce cost of any silver format but maximum liquidity and sovereign backing. A 100 oz bar is the opposite pole, minimum cost, minimum flexibility.
