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 10 oz JM Bullion Silver Bar is the second bullion product carrying the JM Bullion brand, and has been produced since 2017.
The company says about it:
Silver bars are one of the most coveted means of investing in silver bullion. When investors search for silver bars for sale, it is often the 1 oz or 10 oz weight that they turn to as an ideal balance between value and pure silver content. Right now, JM Bullion is proud to announce the issue of its first-ever 10 oz JM Bullion Silver Bar.
JM Bullion is proud to have reached a level in the precious metals industry where it can serve the needs of gold and silver lovers as an authorised online dealer, and also bring them a unique product that buyers can use to showcase their pride in buying from a particular vendor. With the release of the 10 oz JM Bullion Silver Bar, you not only get 10 Troy oz of .999 pure silver, you get a truly unique item.
The bar is manufactured by Sunshine Minting. |
