100 oz Red River Mint Silver Bar

The 100 oz Red River Mint Silver Bar

The 100 oz Red River Mint bar is a .999 fine silver bar in the largest standard retail bar size. At 100 troy oz (3,110.35 g, about 6.86 lbs) it concentrates a substantial silver position into a single piece roughly the footprint of a large smartphone, though far heavier at around 3.1 kg. The 100 oz format is a standard unit of trade in the North American silver market, and every major bullion dealer buys and sells bars of this weight.

The case for the size is cost efficiency. The fixed costs of manufacturing, assaying, and packaging are spread across 100 ounces, which makes 100 oz silver bars the lowest per-ounce premium of any standard retail silver bar size, typically 2-4% over spot under normal conditions, against roughly 4-8% for 10 oz bars and 8-15% for 1 oz bars. For accumulators building positions of 500 oz or more, that compression adds up quickly.

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. Most dealers will also weigh, measure, or assay a secondary-market 100 oz bar before purchasing, an extra step compared with coins of known specification. Buyers wanting flexibility alongside bulk often pair a large bar with smaller silver bars for incremental liquidation.

100 oz Red River Mint Bar Specifications

The bar contains 100 troy ounces of silver at the .999 fineness that is the standard purity for this weight class. Dimensions for 100 oz bars vary by manufacturer but are roughly in the region of 140 x 80 x 25 mm. There is no standard tube or roll packaging at this size; 100 oz bars are sold individually, sometimes in protective plastic sleeves.

At around 3.1 kg the bar is manageable for home storage and fits in a safe or safe deposit box, though stacking multiples adds weight quickly. Most 100 oz bars are rectangular and stackable by design. As with all silver, dry storage matters: silver tarnishes when exposed to sulphur compounds, so bars should be kept wrapped or sleeved, ideally with anti-tarnish protection.

Tax Treatment of the 100 oz Red River Mint Bar

As a .999 fine silver bar with no legal tender status, this product follows standard silver bullion tax rules, and at roughly $3,300 in value per bar (at ~$33/oz silver) it clears most US threshold-based exemptions in a single purchase.

• United States: No federal sales tax; treatment depends on the buyer's state. Around 35 states exempt bullion outright, and the threshold states (California over $2,000, Florida over $500, Louisiana, Massachusetts, and New York over $1,000) are all cleared by a single 100 oz bar at current prices. Long-term gains are taxed at the collectibles rate of up to 28%.
• United Kingdom: New silver bars carry 20% VAT, and with no legal tender status there is no CGT exemption. The UK and Europe also generally prefer kilo and metric bars over the 100 oz format.
• Canada: Silver refined to at least 99.9% purity in bar form is GST/HST exempt, so the .999 bar qualifies.
• Australia: Silver of at least 99.9% purity in tradeable form is GST-free; .999 meets the threshold.
• New Zealand: Silver of at least 99.9% purity is GST-exempt.
• Singapore and Hong Kong: Singapore exempts qualifying investment silver (99.9% minimum) from GST; Hong Kong has no sales tax or import duty. Neither taxes capital gains.

Red River Mint 100 oz vs RCM, Asahi, and Smaller Formats

The main brand alternatives at this weight are LBMA-accredited refiner bars. The Royal Canadian Mint 100 oz bar is struck at .9999 fineness, serialised, and LBMA Good Delivery listed. Asahi Refining, successor to Johnson Matthey's precious metals business, produces a current 100 oz bar that is widely distributed in North America. Discontinued Engelhard and 1980s Johnson Matthey bars trade with collector premiums on the secondary market. Bars from LBMA-accredited refiners command tighter buyback spreads, with major dealers typically paying 1-3% below spot for recognised brands; bars from lesser-known producers remain liquid but may face wider buyback discounts and typically sell at melt value with no brand premium recovery.

Against smaller formats, the decision is premium versus flexibility. A 10 oz silver bar runs around 4-8% over spot and can be sold piece by piece across ten bars for the same total weight; the 100 oz bar compresses the premium to roughly 2-4% but locks the position into one indivisible unit. The marginal saving from 10 oz up to 100 oz is also smaller than the saving from 1 oz up to 10 oz, so the larger format mainly suits committed accumulators. The kilo bar (32.15 oz) is the international middle ground and the preferred large format in Europe, Asia, and Australia, while 100 oz remains the North American standard.
