Platinum
Platinum bullion encompasses coins, rounds, and bars struck or cast in .9995 fine platinum, the highest purity standard common to modern platinum bullion products. As the rarest of the precious metals traded in numismatic and bullion markets, platinum occupies a distinct niche between gold and palladium, prized for its density, corrosion resistance, and industrial significance alongside its role as a collectible and store of metal value. The category includes sovereign-minted coins such as the American Platinum Eagle — the only platinum coin backed by the U.S. government — as well as the Canadian Platinum Maple Leaf, the Isle of Man Noble, and various other government-issued platinum coins. The American Platinum Eagle, introduced in 1997, is struck in 1 troy oz, 1/2 troy oz, 1/4 troy oz, and 1/10 troy oz denominations in both bullion and proof finishes, while other world mint programs offer their own weight and denomination structures. Private mint platinum rounds and bars round out the category for buyers focused primarily on metal weight. On CoinDuffle, the Platinum category brings together listings from multiple vetted dealers, spanning annual bullion strikes, collector-grade proof issues, fractional weights, and larger-format bars. Buyers will find a range of years across ongoing series as well as older or limited-issue releases. Sub-categories may include Platinum Eagles, Platinum Maple Leafs, Platinum Bars, and Platinum Rounds, making it straightforward to browse by product type or series.

Frequently asked questions
The overwhelming majority of modern platinum bullion coins and bars are struck or cast to .9995 fineness (99.95% pure platinum). This standard is used by the U.S. Mint for the American Platinum Eagle, the Royal Canadian Mint for the Platinum Maple Leaf, and most other sovereign and private mints producing platinum products. Some older or specialty issues may vary, but .9995 is the recognized benchmark for the category.
Platinum coins from sovereign mints most commonly come in 1 troy oz, 1/2 troy oz, 1/4 troy oz, and 1/10 troy oz sizes, each carrying a face value denomination in the issuing country's currency. Platinum bars and rounds from private mints are available in a wider range of weights, from fractional sizes up to 10 troy oz or larger, without a stated face value.
The American Platinum Eagle, minted by the U.S. Mint since 1997, is the most widely traded platinum coin series in North America. The Canadian Platinum Maple Leaf, produced by the Royal Canadian Mint, is also commonly found. Other series — including the Australian Platinum Platypus and the Isle of Man Platinum Noble — appear less frequently and are often sought by series collectors rather than bullion buyers.
