An easy question: I have 2 $5. chips from the Avi Casino in Laughlin, Nv. On the Obverse of one of the chips are 4 White/Yellow inserts. On the Obverse of the second chip are 4 Yellow/White inserts. Everything else is identical. Do chip collectors consider these only one chip? Or, because the colors of the inserts are reversed, are these considered two different chips? Thanks. Doug McKenzie
