But unless you to review the markings and research it, it may have been when ppl were selling everything so it could be sterling silver right? or some other silver alloy. Ppl were selling jewelry, watches, silverware, plateware, etc when silver was high. I had ppl I knew selling anything and everything silver that they had. Crazy. So a generic silver bar would have me double guessing what it actually is without confirming each and every identity mark on it. Then I'd still pass and get gov't issue silver.
