1 oz Scottsdale Stacker Gold Round

Stackable Gold with Interlocking Design

The 1 oz Scottsdale Stacker Gold Round contains 31.1035 grams of 999.9 fine gold, produced by Scottsdale Mint in Scottsdale, Arizona. The round is part of the Lion Stacker series, Scottsdale Mint's signature product line defined by precision-engineered interlocking edges that allow rounds to nest securely when stacked. The concave and convex surfaces on the top and bottom of each round create a physical interlock, unlike flat rounds that simply sit on top of one another.

Scottsdale Mint was founded in 2008 by Josh Phair, formerly a VP at Willis Towers Watson managing North American mining practices. That background in mining industry risk management is reflected in the engineering-first approach to the Stacker design. The mint holds ISO 9001:2015 certification, and all products are manufactured on-site in Arizona using CNC minting equipment from raw materials stored at the facility.

The Stacker concept has become so closely associated with Scottsdale Mint that the company has trademarked the name. The Lion Stacker rounds come in four sizes: 1 oz, 2 oz, 5 oz, and 100g. All four sizes share the same 38.8 mm diameter, with only thickness varying by weight. This means a 1 oz round, a 2 oz round, and a 5 oz round can all interlock within a single stack, which is unusual for bullion products and a genuine storage innovation.

Scottsdale Mint produces to order rather than holding finished inventory. This means delivery times can extend to 4-6 weeks during periods of high demand. For buyers accustomed to the overnight shipping of major dealer inventory, this is worth noting. The obverse features the Scottsdale Lion in high relief, while the reverse carries weight and purity markings.

Lion Stacker Round Range

The cross-denomination stacking works because all rounds share the same diameter. Only thickness increases with weight. The interlocking mechanism uses concave and convex surfaces rather than the rectangular bevels used in Scottsdale's Stacker bars. Note that the rectangular Stacker bars (10 oz, kilo, 100 oz) use a different interlocking system and do not interlock with the rounds.

Scottsdale Mint also produces gold Stacker bars in 1 oz, 5 oz, 10 oz, and 20 oz sizes, which feature serial numbers, anti-forgery swirl patterns, and the rectangular bevel interlocking design.

Scottsdale Stacker vs Standard 1oz Gold Rounds and Coins

The 1 oz Scottsdale Stacker sits in the private-mint gold round category, competing with generic rounds from Sunshine Minting, SilverTowne, Asahi, and Highland Mint. All produce 1oz gold rounds at 999.9 purity with premiums of approximately 2-5% over spot. The Scottsdale Stacker typically commands a slight brand premium above the cheapest generic rounds, reflecting the interlocking design and the recognisable lion hallmark.

The interlocking feature is the Scottsdale Stacker's genuine differentiator. Most generic rounds are flat on both sides and simply sit on top of each other in a tube. The Stacker's concave-convex surfaces create a physical interlock that prevents sliding and provides more stable stacking. For vault or safe storage of multiple rounds, this is a practical advantage, though the price premium above a basic generic round may or may not justify it depending on the buyer's storage needs.

Against sovereign mint coins like the 1oz American Gold Eagle, 1oz Britannia, or 1oz Maple Leaf, the Scottsdale Stacker loses on liquidity, legal tender status, and tax advantages (no CGT exemption in the UK, more limited IRA options in the US). Sovereign mint coins carry premiums of 3-8% but offer government backing, advanced security features, and tighter buy-sell spreads at resale. The Stacker's advantage is a lower acquisition premium, partially offset by potentially wider spreads when selling.

The production-to-order model is another consideration. Scottsdale Mint does not hold finished inventory, so delivery can take 4-6 weeks during demand spikes. Major dealers stocking sovereign mint coins typically ship within days. For buyers who need immediate delivery, this can be a meaningful drawback.
