I have stopped. I started collecting them about five years ago and found that I was overwhelmed. I then reduced my LE's to a few select hotels plus A.C. I collect from hotels I stay at or play at. I dumped about 100 of them last fall at near face. My original intent in collecting Nevada chips was to try to get one chip from each casino--an impossible task but one totally without my reach if I had to choose between spending $100 a month on some new LE's or on a couple of chips from closed hotels. I chose the latter route.
