I am looking at this 10 oz. Johnson Matthey bar, and am wondering if this is normal or within the boundaries of what is acceptable. I am seeking the opinions of those intimately familiar with cast gold bars in general, and especially those from Johnson Matthey. The bar on several scales shows a weight just a hair under 10 ounces, 9.997 ounces as close as I can determine. In the real world, do some bars weigh just under by this small amount? One edge on each end is finely filed, and I understand that is done on some cast bars to bring a heavy bar to weight. Are 10 ounce Johnson Matthey bars often, typically, or sometimes weight-adjusted in this way? Is this a concern? If you had a bar as described in hand, would you return it if it were an option? Or, is this normal and acceptable by real world standards? Thank you.
