What is the difference between the Bally's Mikohn Safejack chips? Seems as if this question is asked every so often, just the other day in fact! Uhh, the squares are different sizes is the answer but I've never seen an illustration. Well. Finally got one of the other variations today. Posted below (Quack Attack posted above) and you can tell the the slight diff between teh '96 and '97 versions. There. I feel better now.

Bought my first one way back when I was starting out from Mike Spinetti on eBay. Remember Mike's wrap jobs on his eBay shipments? About six yards of that free USPS Priority tape and half the anticipation of freeing your next Spinetti prize was seeing if you could do it without risk to digits, dignity or clay! Mike was a very good eBay'er BTW. Here's the writeup Mike had on his auction for my first Safejack:

"The big chip with a little chip inside" - a computer chip that is! Used on only three tables in 1996 at Las Vegas' Bally's as an experiment (beta test), the table was rigged with lights and a shoe that registered the card as it came out of the shoe. Your chips were counted and your bet recorded. And a red light came on telling you, you had just busted, even before the card out of the shoe got fipped over. Because the chips were expensive, you couldn't walk with the chips but had to cash them in at the table for regular house chips. But as I pointed out the flying pigeon overhead to everyone at the table, I pocketed one $5 chip for me and an extra for you.
P.S. Big Brother Blackjack was a flop, and the game removed.
