They will be obsolete on the date each gambling jurisdiction so says they are obsolete, and they will have no monetary exchange value for any currency used at that casino once they become obsolete (pasé); replaced with something newer in this case, and they will no longer be used at play on any table in that casino (unless revalued as was the case in the 1961 French Monetary Reform Act where every 100 French francs then became 1 New franc (NF) by means of a comma struck in the numeral denomination or the new value struck on the piece, solely.
I strongly suggest that when the CC>CC Officers accept the glossary of terms and words related to gambling that is now being compiled, that the word "OBSOLETE" be part of that glossary; only because it's a commonly used word concerning gambling chips no longer in use.
