Just a suggestion ...
Before turning any silver strikes back to the cage for face value ... why not offer them at face value (plus actual postage/insurance costs) to collectors on this message board?
One thing casinos hate to see (whether it be chips or tokens intended for collectors) that were removed by collectors ... is to be turned back into the cage. I personally believe this is one reason why very few A.C. LE chips have been issued recently. Only one LE chip has been issued so far this year in A.C.
