Hi. I collect 10 oz silver cast bars by different Manufacturers/companies. I have: Scottsdale, Ainslie, Englehard, As good as gold, Perth mint, Southern Cross bullion, Regal metals, Gold bullion Australia, ABC bullion and Academy 10 oz cast bars. I am willing to pay spot plus 15% plus postage for any 10oz silver cast bars I don't currently have. Please PM me. Thanks
