Jay's comment on attending an Atlantic City chip club meeting is a good idea.
Here's posting on the dates for upcoming meetings:

For Joanna:
Getting a variety of opinions is good start. I'm in California, so not near you. But I would be glad to look at pics of the chips and offer opinions. No charge. I'm not an appraiser, but I've been around chipping for quite a few years (30+ years).

Good luck with the collection, whatever you decide to do.
