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.
This 1 oz Silver Investment Bar featuring Archangel Michael was first issued in 2021.
Scottsdale Mint says about it:
Archangel Michael is most often thought of as the angel of protection and the most powerful of all the angels. He is considered a leader within the angelic realm and a patron angel of righteousness, mercy and justice. As such, scriptural artwork depicts him as a warrior most often carrying a sword. Michael leads God’s armies against Satan’s forces in the Book of Revelation, where during the war in heaven he defeats Satan.
