I studied my NV Checks and Chips book - and yes - many BJ chips have CI's (you just can't see them all like you can with a Stardust CI or Freemont CI or Jerry's in NLV.)

BUT they didn't use coin inlays in their hotstamp chips (did they??)... didn't they use plastic? (interlocking puzzles or something???)

If B&G has been doing coin inalys all along - what would be a common (?) example of one?
If I had to guess - I'd guess they cornered a corner in the foreign market?

or are we talking internal CI's - not shiny metal you can see-type chips?
