John ... like the coin dealers tables I used to avoid when I was actively involved in collecting bust half dollars ... you know; the ones with all the bright and shiny cleaned coins? I also stay away from chip dealer tables whose entire chip inventory are nice appearing worn, but cleaned, chips ...
"because they sell better at higher prices when they look nice and clean".
Folks ... if you insist on purchasing cleaned chips ... buy the dirty ones .... then do the cleaning yourself if you must. You'll save yourself a pile of money!!
