I just returned from Vegas and got a 200.00 ss from the Imperial Palace....no number on the ss or on the box....I did not notice this until I got back to the hotel and looked at it, for I already had the ss but got enough 10.00 ss won to get the 200.00 at a good price....does anyone know the value on something like this? It is the first one I have seen like this....Bob Chambers told me it was a prototype of the 200.00 ss before numbers are put on them....please advise if you have any info on this....Thanks Christine
