"The best advice, collect what you like, Don't treat it as an investment but rather as the hobby it is meant to be and you will be better off." ... Bob Touts

I would add one more thing ...
After your collecting days are over, or should you lose interest in your hobby and the need arises to dispose of your collection, undoubtedly there will be some chips that are worth more than others. Accept that as a bonus to the many years of satisfaction and enjoyment that you've had while assembling your collection and making friends and trading aquaintances.

If you're in this hobby for the short run as an investmemt ... you're probably going to be disappointed at the end if you've only been assembling LE's.

Generally speaking, the fact is that it is the older regular table issues in EXCELLENT CONDITION which have been traditionally neglected that attracts the big money... especially the higher denomination chips that are ignored while they are on the tables. Everybody wants the regular issue chips (after the chips have gone obsolete). Condition plays a BIG part in finding buyers for well-preserved table specimens of a decade or more ago. Today's collectors are the preservationists for the chip collector of tomorrow.

Just a personal observation for whatever it's worth.
