Just thinking about those Mirage "Poker" $1 chips that were introduced in the Poker Room a couple of years ago.

I don't know the total order quantity (probably quite large), but it was discovered that the inlay that's supposed to say "Poker" on both sides also came out it a 1-sided error and also a double-sided error, without saying "Poker".

Here's the chip I'm referring to -- with and without the Poker notation (pics from MOGH/ Chip Guide):

Anyway, the theory is that on each sheet of inlays (sheet of 20?) there was one (or maybe more than one?) image that didn't include the "Poker" notation, in error.

Just assuming the 1-in-20 error ratio, when the inlays were cut from their sheet, there was a 95% random chance that both sides would be correct; a 5% (rounded) chance for a 1-sided error and a 0.25% chance for a double-sided error.

Or, assuming every 4 boxes (= 400 chips), 380 would be correct, 19 would be 1-sided error, and 1 would be a double-sided error.

All this is based on random distribution, but with a large order, those relative numbers may be pretty close ... IF the assumption of 1 error per page of 20 inlays is correct.

Just musing about this on a Sunday night. No real point to make, except that the errors, especially the double-error chips are likely rare to very-rare!
