About the 2 oz Eagle Stacker Silver Round
The 2 oz Eagle Stacker Silver Round
The Eagle Stacker is the flagship of Scottsdale Mint's Stacker line, struck in Scottsdale, Arizona. Its defining feature is a patented interlocking mechanism: the obverse is convex, the reverse is concave, and when one round is placed on another the raised side nestles into the recessed side and locks with a click. The design is functional as well as decorative; stacked rounds take less space and sit more stably than loose rounds in a tube.
The 2 oz version contains two troy ounces (62.21 grams) of .999 fine silver. It shares its 38.5mm diameter with the 5 oz Eagle Stacker, differing only in thickness, which is what allows the multi-size stacking: the 1 oz, 2 oz and 5 oz silver rounds all interlock with each other, and Scottsdale sells a Trio Set of the three sizes designed to lock into a single stack. The 1 oz copper and antique silver variants stack with the silver too; only the 1 oz gold version is limited to stacking with its own kind.
The obverse carries a helmeted, front-facing American bald eagle in near-sculptural ultra-high relief, achieved through multiple strikes during minting. That extra production effort is part of why the Eagle Stacker commands a higher premium than flat-struck generic rounds. The design does not change year to year, and the rounds are distributed through major dealers as well as Scottsdale Mint's own site, which ships globally.

The 2 oz and 5 oz rounds share the 38.5mm diameter and differ in thickness, while the 1 oz is slightly wider at 39mm yet still interlocks with both. As a private round it carries no government security features such as Bullion DNA or Mintshield; authentication rests on weight and dimension checks, the magnet slide test, sigma testing, and the stacking mechanism itself, since a counterfeit would need to replicate the precision concave and convex engineering to interlock properly. Scottsdale Mint holds a patent on the stacking design.
Tax Treatment for the Eagle Stacker Silver Round
Silver rounds are taxed like silver bars everywhere; the round shape earns no coin privileges because there is no legal tender status behind it.
- US: The Eagle Stacker's primary market. Most states exempt bullion from sales tax, though some tax it or exempt only above purchase thresholds. Long-term capital gains are taxed at the collectibles rate of up to 28%. The .999 purity meets the IRS fineness requirement for silver IRAs, but acceptance of private-mint rounds depends on the custodian.
- UK: 20% VAT on purchase, plus CGT liability on sale since the round is not legal tender. That double hit makes rounds hard to justify against CGT-exempt silver Britannias for UK buyers.
- Canada: 0% GST/HST for silver at 99.9% purity or higher, which .999 meets.
- Australia: GST-free as investment-grade silver at 99.9% purity or higher.
- New Zealand: GST-exempt at 99.9% purity or higher; no formal capital gains tax.
- Singapore: Qualifying silver of 99.9% purity or higher is GST-exempt under the Investment Precious Metals scheme, and there is no capital gains tax.
- Hong Kong: No sales tax, no import duty, no capital gains tax.
- EU: Full national VAT applies to silver, typically 17-27%, with no margin scheme benefit since rounds are not second-hand coins.
Eagle Stacker vs Generic Rounds and 2 oz Coins
Against standard generic silver rounds from mints like Sunshine, Asahi or SilverTowne, the Eagle Stacker costs more. Generic rounds are flat-struck and do not interlock; the Stacker's ultra-high relief and patented mechanism justify its markup only if the design and stacking utility matter to you. Buyers chasing maximum ounces per dollar will do better with generic rounds, which typically run 5-10% over spot, or with silver bars at lower premiums still.
The 2 oz weight itself invites comparison with sovereign 2 oz coins. The Royal Mint made 2 oz a mainstream silver weight with the Queen's Beasts series (2016-2021) and continues it with the Tudor Beasts, both struck in .9999 silver, while the Perth Mint issues 2 oz coins in its Lunar and Koala ranges. Those carry government backing, higher purity and, for UK buyers, CGT exemption as legal tender, but they also carry coin premiums. The Eagle Stacker offers the large-format canvas at private-round pricing instead.
Within Scottsdale's own line, the Eagle Stacker supersedes the original Stacker round, which used a simpler concentric-circle design with the same interlocking concept. Some sovereign mints have flirted with stackable designs, such as the Fiji Taku, but the combination of functional stacking and high-relief artwork remains unique to the Stacker line. Resale follows the usual private-round pattern: recognised-brand rounds sell to any reputable dealer, recovering part but not all of the purchase premium, and tubes or multi-piece stacks trade efficiently.
