LIMITED AVAILABILITY. From time to time we have stock of Stackers that we've purchased back from our customers. While our other offerings are newly minted, these silver bars may exhibit toning due to the natural oxidation process (similar to silverware, silver jewelry, etc.) but have no effect on the value of the silver. These bars are secondary market bars and may have nicks and scratches. They are priced accordingly. Many of these are coming in from various vaults around the world and if for some reason it takes too long to clear customs, we will provide a new kilo bar. This is a stock photograph but you will receive a genuine 1 Kilo Scottsdale Stacker which is 100% Guaranteed by our company as authentic .999 Fine Silver, Minted by Scottsdale Mint in the USA.
