Sunshine Minting was founded in 1979 in Idaho and has grown into one of the larger private mints and refiners based in the United States, producing both its own branded bullion bars and blanks used by other mints and government programs. Unlike a Swiss refiner built primarily around wholesale bar refining, Sunshine Minting's business spans minting blanks for coin programs as well as its own retail bar and round products, giving it a somewhat different footprint in the US bullion market than the European Good Delivery refiners collectors more commonly hear about.
Sunshine Minting bars are best known among collectors for a specific anti-counterfeit feature: a hidden 'Mint Mark SI' that is invisible under normal light and only becomes visible under ultraviolet light, giving buyers a way to check authenticity without special equipment beyond a UV flashlight. This feature has made Sunshine Minting bars a common recommendation for buyers who want a US-produced, easily-verified bar without needing a smartphone-based scanning app. Recognition is strong within the US market specifically, though somewhat less internationally uniform than the longest-established Swiss refiner brands.
