I, too, am puzzled about the so-called new and old Bighorn $1 chips. Even went there to see for myself when in Las Vegas for the Casinorama Show. Only thing I could notice was that the outer rings on the new ones contain sparkly silver grit in the grey material. That's harder to spot on the old worn-down chips. Did the old chips also sparkle when new? Mr. Ram looks the same on both.
