Tarl, no it is not a silver strike. However it is as you know .999 fine silver. It was gotten originally out of the gift shop. They were made in 1/2, 1 and 2 ounce sizes. They generally sell for a little over silver melt value as so many were produced and are out there. They were made in the Stagecoach, Pony Express and Casino designs.
Hope this helps,
