In the United States, a significant number of private mints produce bullion which is not legal tender and is targeted at investors and not at coin collectors - such as this one.
The 1 oz JM Bullion Silver Bar has been produced since 2019.
The company says about it:
When it comes to buying silver bars online, investors will find a wide range of options. You can purchase silver bars with unique designs or simple bars that have only markings identifying weight, purity, and metal content. For fans of JM Bullion, you can even showcase your pride in purchasing precious metals from JM Bullion with a new version of our branded silver bar.
These silver bars have frosted background fields with slightly mirrored design elements. Whether a bar is finished with proof or reverse proof elements, the idea is to create a sense of visual separation between the surface areas and designs or engravings. The mirrored appearance of the engravings on these bars helps them jump out and catch the eye against the frosted background field.
1 oz JM Bullion Silver Bars are produced by SilverTowne, the private mint in Indiana that started as a small coin shop in 1949. Today, the Winchester, Indiana, company is one of the nations leading private mints.
