actually quite a bit smaller than you predict. Not sure if anyone was "keeping score" as to the number of No-Pokers found (whether one side or both) but remember not a lot of them seemed to turn up.

Someone suggested I buy an entire rack of chips and look through them (perhaps on the assumption that the errors would be that common).

So, when next in Las Vegas, about a month or two after the discovery . . . I sauntered into the Mirage and asked to buy some poker chips, say 100. And the manager scowled and replied, "We cannot sell them. You get them at the tables after you sign in to play!"

I think by then they were wise to us!

And as far as I know, not another Non-Poker error ever came to light. Mirage poker room employees De-Non-Pokerized the set? (There's another newly invented word for ya.)
