100 oz Continental Coin & Jewelry Co. Silver Bar

The 100 oz Continental Coin & Jewelry Co. Silver Bar

This bar packs 100 troy ounces of .999 fine silver, roughly 3.11 kg, into a single piece of metal. The appeal is straightforward: the 100 oz format carries the lowest per-ounce premium of any standard retail silver bar size, typically 2-4% over spot. The fixed cost of manufacturing, assaying, and packaging gets spread across one hundred ounces instead of one, which makes this format the most cost-efficient way to accumulate physical silver in retail quantities. By comparison, 1oz silver bars often run 8-15% over spot and 10 oz bars run 4-8%.

The trade-off is divisibility. A 100 oz bar is indivisible; selling means finding one buyer for the full amount, where a stack of smaller bars or coins can be parcelled out over time. The weight class suits accumulators building silver positions of 500 oz or more, for whom the premium savings are significant. Occasional buyers, or anyone planning to sell incrementally, get more flexibility from 10oz silver bars or 1 oz coins.

The 100 oz weight is a standard unit of trade in the North American silver market, and every major bullion dealer buys and sells bars at this size. Brand recognition does affect resale: bars from LBMA-accredited refiners command tighter buyback spreads, while bars from smaller private producers may face wider discounts and will usually be weighed, measured, or assayed by the dealer before purchase. That extra verification step is the cost of buying outside the big refinery names, and it should be weighed against any purchase price advantage.

100 oz Silver Bar Specifications

Dimensions for 100 oz silver bars vary by manufacturer, but a typical footprint is roughly 140mm x 80mm x 25mm, comparable to a large smartphone in footprint though far heavier in the hand. At around 3.1 kg per bar, a single piece is manageable in a home safe or safe deposit box, but stacking multiples adds weight quickly. Most bars at this size are rectangular and stack cleanly, though some cast bars have irregular poured surfaces.

Unlike coins, there is no standard tube or roll packaging at this weight; 100 oz bars are sold individually, sometimes in protective plastic sleeves. Note that the COMEX deliverable size is 1,000 oz, not 100 oz, so this format is a retail and dealer trading standard rather than an exchange standard. The .999 purity meets the common investment-grade benchmark for silver bars, and the format is the most space-efficient way to store silver value, an important consideration given silver's low value-to-weight ratio.

Tax Treatment of 100 oz Silver Bars by Country

Silver bars receive the same headline tax treatment as silver coins in most jurisdictions, but with one consistent disadvantage: no legal tender status, so no access to coin-specific exemptions where those exist.

• United States: no federal sales tax; most states exempt bullion bars, while a minority tax them or apply threshold-based exemptions (New York and Massachusetts exempt purchases over $1,000, Florida over $500, California over $2,000; a single 100 oz bar comfortably clears these). Long-term capital gains are taxed at the collectibles rate of up to 28%. Silver of 99.9%+ purity from accredited refiners can be IRA-eligible.
• United Kingdom: 20% VAT on new silver bars, and gains are subject to CGT since bars have no legal tender status. This makes silver bars the least tax-efficient silver form for UK buyers.
• Canada: exempt from GST/HST as silver refined to at least 99.9% purity in bar form. Gains are taxable at the 50% inclusion rate.
• Australia: GST-free as investment-grade silver (99.9%+ purity threshold for silver).
• New Zealand: GST-exempt at 99.9%+ silver purity; no formal capital gains tax.
• Singapore and Hong Kong: no sales tax on qualifying bullion and no capital gains tax in either jurisdiction.
• EU: full standard VAT applies to new silver bars at national rates (17-27%).

The 100 oz format is primarily a North American product, where the tax picture is most favourable: most US states exempt it and Canada exempts it federally.
