Andy, An issue of 500 LE's at one of the strip casinos may last a day, but not the case in North Las Vegas. Two years ago I was at Jerry's Nugget playing black jack in the middle of the afternoon. When I went to cash in at the cage, the gal asked if I was a chip collector. I said I was in town for the CC>CC show. She went back to the vault & brought out a rack that had all of the LE's the casino ever issued. They may have issued 1,000 or more of each, but they were still available a year or more later.
