No can only cash in from the state that you obtained the chip.
Put it on e bay and maybe you can get face value. Unless you will be back in the next few months.

If the casinoes are the same company.

Casino chips are only valid at the hotel where they are issue. You cannot even cash chips at a different hotel in Las Vegas.

No you can only cash it in at the casino with the name of it. They do not expire

No, you have to take it back to Las Vegas. Even if it is the same casino company I doubt they will cash it.

If it is an old chip it may not have any value at all. The casinos replace their chips from time to time and do not honor old chips after a certian time period. Some old chips have value as collectibles.

No!
Yes! Only from same address casino issued it. From CZRS palace then mail it back certified mail. They should issue you a check. Call ahead for this.

PS old retired chips can have value on Ebay. Resell it at Ebay. 2nd choice!

What sense would that make?

No, each hotel/casino has its own chips. And even if its same casino company, you still would have to take it back to the orginal hotel in Vegas you got it from.

Pennsylvania casinos don’t even issue chips. They can only cash vouchers issued by their casino.

That chip can only be cashed in at the casino where it was issued, or in some cases a sister casino. For example, Binion’s will cash a Four Queens chip because the two casinos are owned by the same company. However, New Jersey law prohibits any casino cashing from another casino’s chips even if they’re owned by the same company.

Put it on Ebay. You might get something for it there. Or if you’re going back to Vegas soon, hold onto it.
