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 Scottsdale Reserve Cast 1 Kilo Silver Bar by Scottsdale Mint has been produced since December 2022.
The Mint says about it:
No two bars are alike and the deep stamped Reserve logo has an honest, mature appearance. Yes, there might be dips, ripples, and burn marks; all not so subtle nods to the old school. This is the RESERVE Cast Bar. Cast by Scottsdale craftsmen resulting in unique beauty with a satin frost finish. Now you can own a bar of a mint style before modern technology.
