If my records are right, I've had the 25K before the shoe went missing in action. Its got he Paulson logo on back (there was a notched one with the same front/back as well). I dont remember when I picked up the 1000 but it had to have been in the last 2-3 years (within the MTR/Harrahs/4Queens reign). So anything is possible of course but I still enjoy the chip....
This is the same artwork they have used on a number of other chips including the Harrahs/MTR $1 design for the re-opening in 2004.
