I usually collect a chip or two from the places that I’ve been and played before - have had these chips at work and shuffle them on a daily basis for probably 10years or so. Anyway, I noticed the 20 stack at work feels smaller than a new stack of chips at home. Last night I brought the shuffle stack home to clean and compared them with and new stacks of Paulson’s - low and behold they have enough wear on them to fit 21 old chips where 20 new ones would fit in a rack....just begs the question...do you think anyone has been ripped off at a casino with very well used chips...especially where larger denominations are concerned?
