Is the casino open? If not, obsolete. If yes, then...

If the casino has them, are they in current use in the casino for any purpose, reasonably expected to ever be used by the casino in the future, or available for sale to the general public? If not, obsolete.

If the casino doesn't have any, what would you reasonably expect them to do if I turned in a rack? Would they use them or sell them to the general public? If not, obsolete.
