Matchbooks are very interesting. They hold a lot of information by often stating the games the casino offers, location, etc. And they help to date themselves with info. like we now have 400 rooms! Its fun to collect them and find all the variants. I collected every variant I could find at one time. We have tons of extras we will ebay- if these auctions go better.
I mostly now collect just one nice one from an early club and many from small towns around Nevada- some of which that is all we have found is a matchbook!
Good luck if you bid and watch for oddball chips up at our Chipsbottles ebay tonight at 6.
