Looks like Gene's chip has a different hot stamp. Notice the letters on Gene's KINGS CROWN chip vs. the other 2 that i have below. Looks like a different font. Also, notice how Gene's chip has "NEV" vs. Nevada spelled out. The mold for the Chiptalk chip was made specifically for the group buy. Gene's chip may have been made for the casino and then canceled, but I am not sure. I think Cale's chip is from the Poker/Fantasy group buy from Chiptalk, though.
