"If a mistake is made on a chip (or a stamp, coin, baseball card, etc), just because the error is not corrected in later prints or editions doesn't mean the object in question is NOT an error; it's just an UNCORRECTED error. If I am wrong in this assumption, please advise (show me your source of information)."

I'll take a shot at this one. IF every item made has the same mistake, it is not a limited unique error, i.e., all of those items known to exist are the same.

Chip issues are miniscule when compared to stamps or coins or cards when looking at numbers issued. Later issues of a corrected mistake will not be identical to the original (minus the mistake) in the case of casino chips, the chip manufacturers make other subtle changes when making a new run of what is supposed to be the same (similar to) chip.

....and, it would be nice if you'd let us know who you are, as Todd suggested.
