Disclaimer: "I like" below refers to chips I think are neat or cool Remember, you asked, lol!

Atlantic City $1, $2.50 & $5 as well as the LE chips I like.
Las Vegas - I particularly like the odd dollar chips but want the $1 chip to go along with it. I have several $5 LV chips that go with either the $1 or the $1 and $2.50 chips.
I collect some Reno chips that I like, such as Mapes, Money Tree and Nevada Lodge and have just a few more Reno chips from different casinos.
I also have sets of chips from wherever, either $1 & $5 or odd dollars with some other chips from the same casino to go with them.
Neat Sailboat and Beach related chips I particularly like.
Colorado chips I like.
Baseball and Football LE chips I like.
Jetons and other Foreign chips I like.
Various chips I like from wherever.
A few different Silver Strikes. I have quite a few to eventually sell because I decided to only keep those I really liked. The SS's I really want but don't have are Excalibur with the exception of Jouster Knight and the Pewter Ceasars Palace strike.
A few tokens I'll probably keep. Somehow I have a fair amount of these.

I find I pair down. Given I learned you can't collect everything I have hundreds of chips to trade with and eventually sell. I just don't feel like trying to sell on Ebay yet. Let me know if you're looking for any obsolete chips. Don't know how many Vegas I have. I have other Nevada obsolete chips. I really need a database but I can't even get mine in cardboard holders, page protectors and binders.
