If it is a $25 token it probably is .999 silver but not a Silver Strike per our definitions. Most of the old casino $25 tokens go for around $50 to $100 if in uncirulated condition. The silver strikes we collect are from the slot machines and are either $7, $10, $20, $28, and $40 denominations. If it is from the old Vegas World (Bob Stupaks) that was there before the Stratosphere it is made of mystery medal and worth considerably less (around $10) because there are a lot available.
