Seven governments mint silver bullion coins that trade globally with tight bid-ask spreads. They all contain roughly the same silver, but premiums, purity, annual mintage amounts, and resale liquidity vary enough to matter when you’re buying in quantity.
The Major Sovereign 1 oz Silver Coins
American Silver Eagle (.999 fine)
US Mint | $1 face value | Since 1986
The best-selling silver bullion coin in the world. Premiums are the highest of any sovereign — typically $4–$8 over spot — reflecting demand and recognition, not superior silver content. Every dealer on the planet accepts Eagles without question. IRA-eligible under IRC §408(m)(3)(A). The Type 2 reverse (2021–present) added anti-counterfeiting reed patterns. For mintage data, see the Eagle mintage guide.

Canadian Silver Maple Leaf (.9999 fine)
Royal Canadian Mint | $5 CAD face value | Since 1988
The purest sovereign silver coin at .9999 fine. The RCM’s security features include radial lines, a micro-engraved privy mark, and Bullion DNA electronic verification. Premiums typically $2–$5 over spot — noticeably less than Eagles for the same (actually slightly higher) silver content. IRA-eligible. The best value sovereign coin for most stackers.

British Silver Britannia (.999 fine)
Royal Mint | £2 face value | Since 1997
Premiums of $2–$4 over spot price — competitive with Maples, well below Eagles. The Royal Mint upgraded to .999 purity in 2013 (earlier years were .958). Post-2021 coins include a latent security feature that shifts at different angles. CGT-exempt in the UK, which supports global demand. IRA-eligible in the US. See our Britannia silver coin guide.
Austrian Silver Philharmonic (.999 fine)
Austrian Mint | €1.50 face value | Since 2008
Often the lowest-premium sovereign coin, sometimes dipping below $2 over spot. The design hasn’t changed since introduction — no collector premiums on specific years, which keeps secondary pricing tight. IRA-eligible.
Australian Silver Kookaburra (.999 fine)
Perth Mint | $1 AUD face value | Since 1990
Annual reverse design changes create collector demand. Mintages are lower (300,000–500,000/year vs. millions for Eagles/Maples), and older dates carry premiums above melt. Premiums $3–$6 over spot. Not the cheapest stacking option, but the annual designs give upside if collector demand materializes. IRA-eligible.
Australian Silver Kangaroo (.9999 fine)
Perth Mint | $1 AUD face value | Since 2016
Perth Mint’s stacking coin — .9999 purity like the Maple, premiums of $2–$4 over spot, higher mintages than the Kookaburra. Annual design changes without the same collector premium. IRA-eligible.
Mexican Silver Libertad (.999 fine)
Casa de Moneda de México | No face value | Since 1982
The lowest annual mintages of any major sovereign — sometimes under 500,000 BU. That scarcity pushes premiums to $6–$12+ over spot, with older dates commanding multiples of melt. No face value means Libertads are generally not IRA-eligible. Buy for premium appreciation potential, not cost-efficient stacking.

IRA holdings: All qualify except Libertads. Most custodians prefer Eagles and Maples.
Collector upside: Libertads and Kookaburras. Low mintages and annual designs create secondary-market premiums other sovereigns don’t develop.

How Premiums Work
Every 1 oz silver coin trades at spot (currently 73.88) plus a dealer premium covering production, margin, and a recognition/scarcity factor. Premiums compress in oversupplied markets and expand when demand exceeds mint production.
