I assume when you say "edge spots" you're talking about inserts. Right???

I looked over my chips and here's is what I found:

• Harrah's-Reno/Tahoe; $0.25; N5140; Pink chip with 3 White & 6 Lavendar
  
• Harrah's-Reno/Tahoe; $0.25; N5130; Pink chip with 3 White & 6 Navy
  
• Artichoke Joe's-Carson City; $0.50; N7370; Yellow chip with 4 Day Blue
  
• Harrah's-Reno; $0.50; N2325; Lt Yellow chip with 4 Black
  

I am sure there are others but this is what I have.

Cheers!
