I don't really collect matchbooks like some of you who will spend serious money for a matchbook (I enjoy looking for a bargain for my collection).

The Grand Buffet is listed in TGT (1950 - 1960)
I have no clue on the 22 Club (the gold foil did scan well)
The Trocadero/El Cortez Hotel was around from 1940's - 1950's (from TGT)
The Sands Casino and Motor Inn was around from 1965 - 1980

They are not pristine mint but I think I got a fair deal on them.

Enjoy
