If you want a 70 pound block of silver that is the size of a loaf of bread, the 1,000 oz silver bar is for you!
While we find it easier to handle (10) 100 oz silver bars, the industrial sized 1,000 oz bars are a little less expensive (and far more impressive).
None of the bars are 1,000 oz exactly. They will be +/- 50 oz or so. They trade at the actual weight value per oz.
