Sunshine Mint gold bars are made in the USA out of 99.99% pure gold.
A unique security and authentication feature of Sunshine Mint gold bars is the micro-engraved Mint Mark SI™ security mark. It only becomes visible when using the Sunshine Minting Decoder Lens. Sunshine Mint gold bars contain unique serial numbers as well. Each bar is stamped with the gold weight and purity and includes an assay card as the mint's guarantee. Sunshine Mint gold bars are enclosed within tamper-proof packaging. Larger gold bars are generally available for lower premiums over the spot price of gold.
The front of Sunshine Mint gold bars features the mint's name and stamp, showing a bald eagle in flight before a blazing sun. Information about the gold's purity, weight and a unique serial number can be found underneath this design.
The reverse side of each gold bar features a repeating pattern of rising suns as well as the Mint Mark SI™ security feature within a circle at the center.
