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 Square Silver Bar is part of a range of bullion products introduced in 2022 which are branded with the JM Bullion brand - a major US bullion and coin dealer; the bars are struck by Geiger Edelmetalle in Germany.
JM Bullion says about it:
From humble roots in 2011, JM Bullion has grown to become an online leader in the retail sale of precious metals. Among our most popular products are gold and silver bars. After recently celebrating our 10-year anniversary in 2021, JM Bullion is now offering more custom, branded products. 2022 starts with the introduction of JM Bullion Square Bars designed on collaboration with Geiger Edelmetalle.
These bars come with matte surfaces throughout the majority of the bar, while the design elements are struck into the bar and the surface is polished for a glossy finish. Each one also comes with a unique serial number.
