Dave - Yep I remembered to take them out of the holders and you were right, they are all from one casino and that is Harveys, Tahoe. I am going to check some others that another collector has tomorrow and see. One thing I know for sure now is that my scale I am using is only off.01 gram, I know this because I just got back from a shop who certifies scales and they check mine. The only thing they couldn't do was get it to read perfect.
