World silver coins span government bullion issues, such as the 1 oz Australian Silver Kangaroo and Canadian Silver Maple Leaf, and legal-tender collectibles such as the Royal Canadian Mint's $20 fine-silver series, which pairs .9999 silver with collectible designs at accessible prices. The Kangaroo is struck by the Perth Mint, and the $20 coins are legal tender whose face value is symbolic. Every listing states mintage, purity and packaging.
As with U.S. silver, .999-fine 1 oz coins from foreign mints generally meet IRS fineness standards for self-directed IRAs; lower-weight or non-bullion issues are collector pieces. Maple Leafs and Kangaroos are standard examples of qualifying coins. Confirm eligibility with your custodian before purchasing, since accepted products vary by custodian.
