I was able to purchase all six new Las Vegas Hilton Silver Strikes from the "dealers" cage, behind the main cage last May 1998: Barron's Club, H Logo, Starquest (24th Century) Logo, New Hilton Logo, Mr. Barron, and Pot of Gold.
The sad part was it cost me $60.00. The happy part was it didn't cost me $61.00 to play the machine to get all of them.
