The Sunshine Mint, sometimes known in the industry as Sunshine Minting, has been producing magnificent silver bars since it started minting in 1979. Today the mint is celebrated for its product excellence and outstanding designs. Sunshine Silver Bars also boast the mints security features; the bars are engraved with Mintmark SI technology. These engravings are only visible through the specially designed Sunshine Decoder Lens. This technology is regarded as state-of-the-art and is another reason why Sunshine Mint is one of the most renowned mints in the industry.
