2 oz Scottsdale Stacker Silver Bar

The 2 oz Scottsdale Stacker

The 2 oz Scottsdale Stacker is the two-ounce entry in Scottsdale Mint's signature Stacker line, the product family that defined the interlocking-bullion concept in the market. Scottsdale Mint is a private mint based in Scottsdale, Arizona, founded in 2008 by Josh Phair, and every Stacker is manufactured on-site in Arizona using CNC minting equipment. The mint holds ISO 9001:2015 certification and produces to order from raw materials stored on-site rather than shipping from finished inventory, which can extend delivery times during demand spikes.

The defining feature is the interlocking design. The 2 oz piece belongs to the Lion Stacker family, where the interlocking mechanism uses concave and convex surfaces so that each piece nests securely into the next. Because the 1 oz, 2 oz, 5 oz, and 100 g Lion Stackers all share the same 38.8 mm diameter, with only the thickness varying by weight, all four sizes interlock within a single stack. A buyer can mix denominations in one column of metal, something no other major producer's line offers. Scottsdale is the only major producer where the physical interlocking mechanism is the core product feature rather than an afterthought; most stackable products on the market are simply flat pieces that sit on top of each other.

The obverse carries the Scottsdale Lion in high relief, the mint's recognisable hallmark. Mintage is unlimited; this is an open-issue bullion product, not a limited edition, so the appeal is the engineering and the brand rather than scarcity. Each piece is struck in .999 fine silver with precision weight and purity stamping, and 2 oz Stackers ship in tubes of 10. The Stacker name itself has become closely associated with the term stacker in the bullion community (a person who accumulates physical metal), and Scottsdale has trademarked the word for its products.

The case for the 2 oz size specifically is consolidation without losing flexibility. It packs twice the silver of the 1 oz Scottsdale Stacker into a single piece of the same diameter, while still interlocking with the 1 oz, 5 oz, and 100 g sizes. Buyers wanting larger single pieces in the same family can step up to the rectangular 10 oz Stacker bar, the original and most popular size in the line, though the rectangular bars and the round-format Stackers do not interlock with each other.

2 oz Scottsdale Stacker Specifications

The 38.8 mm diameter is shared across the entire Lion Stacker range. The 1 oz, 2 oz, 5 oz, and 100 g sizes differ only in thickness, which is what allows cross-denomination stacking: any Lion Stacker nests into any other via the concave and convex interlocking surfaces. The rectangular Stacker bars (10 oz, kilo, 100 oz) use a different mechanism, a raised bevel on top that nests into a recessed channel underneath, and only stack with identical bars of the same size.

Security on the Lion Stackers relies on precision weight and purity stamping and the distinctive interlocking geometry, which is difficult to counterfeit accurately. Unique serial numbers and the CNC-machined anti-forgery swirl pattern are features of the rectangular bars, not the rounds-format pieces, and Scottsdale does not use a hologram or decoder-lens system. Certi-Lock tamper-evident assay cards with mobile verification are available on some Scottsdale products.

2 oz Scottsdale Stacker Tax Treatment by Country

As a .999 fine silver product from a US mint, the 2 oz Stacker meets the purity thresholds for the main tax exemptions that apply to investment silver, but silver remains taxed at purchase in several major markets where gold is not.

• United States: At .999 fine, the Stacker meets the IRS Section 408(m) threshold for silver (99.9%+) and is IRA-eligible. There is no federal sales tax; state treatment varies, with roughly 35 states exempting bullion, around 10 taxing it, and a handful applying purchase-value thresholds. Long-term capital gains on bullion are taxed at the 28% collectibles rate.
• United Kingdom: New silver carries 20% VAT. With no face value and no legal tender status, the Stacker has no CGT exemption, so gains are taxable at 18% or 24% above the annual allowance.
• European Union: Silver attracts full national VAT rates, ranging from 17% to 27% depending on the member state. The margin schemes available in Germany and the Netherlands apply to pre-owned silver, not new pieces from a dealer.
• Canada: Exempt from GST/HST as refined investment silver of 99.9%+ purity.
• Australia: GST-free as investment-grade silver (99.9%+ purity threshold).
• New Zealand: GST-exempt as fine silver bullion at 99.9%+ purity.
• Singapore and Hong Kong: No tax in either jurisdiction. Singapore exempts qualifying 99.9%+ silver under its Investment Precious Metals scheme, and neither country levies capital gains tax.

2 oz Scottsdale Stacker vs Sunshine, RCM, and Generic Silver

The Stacker's closest private-mint rival in the US is Sunshine Mint. Both are American private mints producing .999 silver, but they take opposite approaches to differentiation. Sunshine builds its case on security: the proprietary MintMark SI system is visible only through a special decoder lens, a more sophisticated anti-counterfeiting approach than Scottsdale's reliance on precision machining and distinctive geometry. Scottsdale builds its case on the physical product: Sunshine pieces have no interlocking design. Sunshine silver is also generally available at lower premiums, so the choice comes down to whether the interlocking storage feature justifies the extra cost.

Against the Royal Canadian Mint, the trade-off is government backing versus engineering. RCM silver is .9999 fine, marginally purer than Scottsdale's .999, and carries the backing of the Canadian Crown, which some buyers prefer for resale confidence. RCM products have serrated edges and serial numbers but no interlocking feature, and the government mint status typically commands higher premiums than private mint output.

Generic silver from refiners such as Asahi or Republic Metals trades closer to spot with minimal premium. The Stacker carries a brand premium for the interlocking design and the recognisable lion hallmark, so a buyer maximising ounces per dollar will do better with generics. What the generic option gives up is the practical storage value of the Stacker design: stable, space-efficient nested stacks rather than loose pieces.

Within the Stacker family itself, the 2 oz sits between the entry-level 1 oz and the 5 oz. All three share the 38.8 mm diameter and interlock with each other and with the 100 g size, so the denominations can be mixed freely. Buyers prioritising lower cost per ounce over cross-size stacking can move to the rectangular 10 oz Scottsdale Stacker, the original product in the line, or beyond it to the kilo and 100 oz King Stacker. More broadly, 2 oz is an uncommon weight for non-coin silver; most refiners jump from 1 oz straight to 5 oz or 10 oz, which makes the cross-stacking Lion range one of the few reasons to pick this weight at all.
