Marv; I believe that "Silver Strikes" is a term that has been adopted by strike collectors. These $2, $7, $10, $20, $40 tokens that are dispensed from special slot machines are more properly called "Premium Tokens" by the casinos themselves. It's like calling all adhesive bandage strips "band-aids" or all pressure sensitive clear tape "scotch tape". Silver Strikes have become a generic term. How many times have you heard Ike Dollars been referred to as "silver dollars"? Even with the new Sacagawea dollars, many folks think they have gold in them.
