Hello guys, I haven't posted for a while but a few days ago I came across something about silver bars that were not .999 silver and were either 90%, 35%, 40%, or .925 (I honestly can't remember if they were for sale, or if somebody just had an idea about this but I can't seem to find it again). Have any of you ever heard of it? If these existed in the market would you buy them? I guess I would be weary about authenticity but if they were sold by a reputable dealer I wouldn't see why not. Thanks and sorry if this post doesn't make much sense haha.
