Bullion
Bullion refers to coins, bars, and rounds valued primarily for their precious metal content — gold, silver, platinum, and palladium — rather than for rarity or numismatic premium. This category encompasses government-issued legal tender bullion coins, privately minted rounds and bars, and specialty pieces that combine bullion-grade metal with collectible designs. Common formats include gold and silver coins struck by sovereign mints, cast or minted bars ranging from fractional to multi-ounce weights, and rounds produced by private refineries in a wide variety of themes and finishes. Within the bullion world, the spectrum runs from purely utilitarian — a simple 1 troy oz .999 fine silver bar — to pieces with significant crossover appeal among collectors, such as licensed pop-culture designs struck on .999 fine silver or copper, limited-edition colorized issues from world mints, and annual series from mints like the U.S. Mint, Royal Canadian Mint, and Perth Mint. Denominations, weights, and fineness vary by metal and issuer: gold bullion is commonly found at .9999 fine, silver at .999 or .9999, palladium and platinum likewise at .9995 or finer. Rounds and bars carry no face value but are denominated by troy weight, while sovereign coins carry a nominal legal tender value. On CoinDuffle, this category spans all six sub-categories — Gold Bars, Gold Coins, Palladium, Platinum, Rounds, and Silver Bars and Silver Coins — sourced from multiple vetted dealers. Listings range from single fractional-weight pieces to multi-coin or multi-bar lots, covering current-year issues, prior-year dates, and specialty releases such as colorized or licensed-design rounds. Buyers will find both standard bullion formats and items with strong collector crossover appeal in one consolidated view.

Frequently asked questions
Bullion coins are struck by government or sovereign mints and carry a nominal face value, making them legal tender in their country of issue — examples include American Eagles, Canadian Maple Leafs, and Britannia coins. Rounds are produced by private mints or refineries, carry no face value, and are not legal tender. Both are typically priced based on their metal content and current spot price.
The Bullion category on CoinDuffle covers four primary precious metals: gold, silver, platinum, and palladium. Each metal is available in multiple formats — coins, bars, or rounds depending on the metal — and spans a range of weights from fractional pieces to multi-ounce issues. Copper rounds, which are not a traditional investment metal but are popular with collectors, also appear within the Rounds sub-category.
The most common weight unit across all bullion is the troy ounce (approximately 31.1 grams). Silver bullion is most frequently found at .999 or .9999 fine; gold at .9999 fine; platinum and palladium at .9995 fine or better. Bars and rounds are also produced in fractional sizes (1/10 oz, 1/4 oz, 1/2 oz) and larger increments (5 oz, 10 oz, 1 kilo), giving buyers flexibility across budget ranges.
Some sovereign mints and private producers apply colorization — a precisely applied enamel or printing process — to standard bullion blanks, or secure licenses to feature pop-culture imagery such as film and television franchises. These pieces meet the same fineness standards as standard bullion but carry additional collectible appeal. The 2026 Niue Star Wars Darth Vader silver coin is a current example: a 1 oz .999 fine silver legal tender coin with licensed artwork.
Bullion bars are produced by refineries and private mints in cast or minted (pressed) form and are denominated strictly by weight rather than face value. They typically carry lower premiums over spot price than coins or rounds due to simpler fabrication. Bars range from small fractional wafers to 10 oz, 1 kilo, and larger formats. They are not legal tender and generally prioritize metal content over aesthetic or collectible design.
