Sir, there was never a silver strike made that was a face value of $25. And from the Stratosphere there were a total of 27 different strikes made. All having a face value of $10. You can get them on Jackpot Auctions or Ebay. They are considered common. The most you should pay is around $12.00. I have most if not all of them and can sell you them for $12.00 each delivered.
