It is posted on jackpotauctions, not ebay. These coins were given as the welcoming gift for Imperial Palace's first $100,000 slot tournament over a year ago. They were never won in a slot machine and have no monetary value. From the information I got there were approx. 500 made and 350 were given out at the slot tournament. The last time I was at the Imperial Palace you could purchase them with your slot points. There was one person who brought 10. They are not considered silver strikes.
