The difference is in the type of hot stamp. The chip you are showing is N9424. It is the very last chip used at Cal's (Jackpot Club). Often Cal would deal to the customers on the weekends. During the week the single blackjack game was shut down.

N8064 has the same hot stamp as the $1.00 Navy. My scanner is down so I can not show you. The name is smaller and kind of inside a shield. Maybe some one will scan the $1.00 navy or the $5.00 green for us. The difference is VERY obvious.
