Nice work Burke, most of the job done here ! =)
To add to your findings :
12 - stralite cruises $500
17 - Le Cove's $25
18 - could be Bluzz at the bend $1
15 - I think I remember a TRK $25 chip with this colors but can't put a name on it
And for the Indian chief's it's tough because a lot of fantasy chips have the exact same paterns, like pharao's $1000 for n°10, Istmuth $5 for n° 6, or Viva las vegas $5 for n°2
Now for the right stack it's even tougher, because there seems to be some customs in here, I can see at least a complete sample set of GCOP, some paulson advertisng chips, and I think I see a Cablanca $500
edit : 13 looks like ceramic, Platinum casino $1 ?
