You may well be right about these particular two strikes but my information about the Caesar's is that many collectors are returning often to play for the 4-in-1 and I would not be surprised if a few people had quite a large supply of these. The number that will "walk" from Tahoe is probably very small. Rarely have I seen people in the Reno area playing strike machines for more than one souvenir coin. It is us collectors that create the reason to issue the chasers. Often times the casino employees do not even know anything about them. Time, of course, well tell, but this has been an interesting thread and I have enjoyed reading the comments...Peter
