Engelhard offered the first silver bullion rounds marketed to the public from 1982 to 1987. These recognizable, privately minted 1-oz. .999 fine silver rounds feature an old-time American prospector hard at work panning for treasure. The silver content is inscribed on the obverse which may vary in design. Produced from a full troy ounce of investment grade .999 fine silver, these rounds are a great way for both investors and collectors to own physical silver.
