Sunshine Mint Ten Ounce Silver Bars
feature a brand new security function, MintMark SI, which is now being incorporated into all new Sunshine Mint bullion products. This new feature is encrypted in the center
on the reverse of the bar, which also depicts Sunshine’s repeating diagonal sunshine pattern.
When viewed through Sunshine Mint’s special decoder lens, the central security design displays the word “valid”, but when the decoder lens is rotated ninety
degrees, a sunburst is displayed. These two different views serve to authenticate the new ten ounce silver bar.
The obverse of these silver bars bears the famous Sunshine Mint eagle along with the sun and its rays in the background in addition to the weight and purity.
