"'If' a casino is going to destroy chips, they submit a letter to gaming with the amounts of each chip destroyed. This is done for auditing purpose.
A casino can remove chips from accountability without destroying them."

A casino submitting a letter declaring the amount of chips to be destroyed still wouldn't indicate how many chips were not destroyed unless they were required to also indicated how many of them were originally made.

I liked your policy of making it known to us how many of the FQ LE's were destroyed.

Does mixing casino chips in the cement used for parking garages count as destroying them, or would that fall under removing them from accountability?

Take care,
