Howdy, what you have is actually not a silver strike. It was given out to all the folks who came to a talk at one of the CC>CC shows. IGT was the speaker. These are clad meaning no silver content. At the bottom you see a RWM which means Roger Williams Mnt. There were 600 made and they came in a red colored capsule. In 2014 the sales ranged from $18 - $62 on eBay.

Hope this helps,
Dennis
