5 oz Imperium Silver Bar

The 5 oz Scottsdale Imperium Silver Bar

The Imperium "V" is the entry weight in Scottsdale Mint's Imperium Collection of cast silver bars, containing 5 troy ounces (155.5 g) of .999 fine silver. The V is the Roman numeral for 5, part of a naming scheme unique in the bullion market that runs V, X, XV, XX, and M (1 kilo) across the collection; "Imperium" is Latin for empire or supreme authority. Each bar carries the Scottsdale lion hallmark, one of the most recognised private-mint marks in the US, against a deliberately raw, industrial cast surface with a blank reverse showing the poured silver.

The 5 oz weight is a middle ground on the bar scale. Premiums for 5 oz silver bars sit between 1 oz and 10 oz pricing, roughly 4 to 7 percent over spot, so the format suits stackers who find 1 oz units too small but do not want the outlay of a 10 oz bar. Cast production also helps on cost: cast bars typically run 1 to 2 percent cheaper than minted bars of the same weight.

The texture is the signature. The bars are made with Scottsdale's V-Cast vacuum casting process rather than machine striking, so each piece carries ripples and subtle surface variations, and no two bars are identical. That unrepeatable surface doubles as a practical anti-counterfeiting feature, and the artisanal look is precisely what cast-bar buyers want over the mirror finish of struck bars.

Imperium V Specifications and the Collection Range

The collection continues upward through the 10 oz "X", the unusual 15 oz "XV" (a denomination almost no other maker offers, sitting between the standard 10 oz and 20 oz weights), the 20 oz "XX", and the 1 kilo Imperium "M" bar. All sizes share the .999 fineness, the lion hallmark, and the cast finish, so a stack across denominations reads as a coherent set. None of the bars is legal tender or carries a face value, there are no assay cards, and bars ship without serial numbers; the casting texture on each piece is the de facto authentication mark.

Tax Treatment of the 5 oz Imperium Bar by Country

The Imperium is a private-mint .999 silver bar with no legal tender status, so standard silver bullion rules apply.

• USA: The primary market. No federal sales tax; most states exempt bullion, but several apply purchase-value thresholds (Florida $500, New York and Massachusetts $1,000, California $2,000), which a single 5 oz silver bar may not clear on its own. Long-term gains are taxed at the collectibles rate of up to 28%. The .999 fineness meets the IRS minimum for silver IRAs, though custodians maintain their own approved product lists.
• UK: 20% VAT on purchase and no CGT exemption, the standard double disadvantage for silver bars.
• Canada: GST/HST exempt under the federal exemption for silver refined to 99.9% or higher in bar form. Capital gains taxed at the 50% inclusion rate.
• Australia: GST-free as investment-grade silver at 99.9% purity in a commonly traded form; CGT applies with a 50% discount after a 12-month hold.
• New Zealand: GST-exempt at the 99.9% silver purity threshold; no formal capital gains tax.
• EU: Full local VAT on new silver bars, 17% to 27% depending on member state.
• Singapore and Hong Kong: No GST on qualifying investment silver in Singapore, no sales tax at all in Hong Kong, and no capital gains tax in either jurisdiction.

Imperium V vs Struck Bars, Stackers, and the 10 oz Step Up

Within the 5 oz weight, the choice is mostly between finish styles. Machine-struck bars from PAMP Suisse bring mirror finishes and assay certificates, and Royal Canadian Mint struck bars add serial numbers; the Imperium offers neither, betting instead on the artisanal cast aesthetic. The same trade appears in resale behaviour: Imperium bars trade at or near melt value on the secondary market, comparable to other generic silver, while LBMA-accredited struck bars recover more brand premium. Buyers also weigh it against fully hand-poured bars from small mints; the V-Cast process produces more consistent dimensions than hand-pouring while keeping the organic texture, and vintage cast bars from Engelhard or Johnson Matthey deliver the same aesthetic only at collector premiums.

Within Scottsdale's own catalogue, the Stacker series bars interlock for secure stacking, which Imperium bars do not; the Imperium is the choice for the raw poured look rather than stacking practicality.

On weight, the natural question is whether to step up. The 10 oz Imperium X generally carries a better per-ounce premium, and the largest single premium drop on the silver bar curve happens between 1 oz and 10 oz. The 5 oz format earns its place as a half-step: roughly half the volume of a 10 oz bar for storage, a smaller single outlay, and finer-grained units when selling, at a modest per-ounce cost. The unusual 15 oz XV gives the collection a further denomination no mainstream rival offers.
