some le's are cashable, some aren't, there is no flat answer to your question. every casino you mentioned (except mgm..i think) has

changed ownership since they were built. also, cashing le's is hit or miss, some cashiers take them, some dont. i recently cashed in about $370

in harrahs las vegas $5 chips that i have been trying to cash for several years to no avail. then on a recent attempt the cage supervisor cashed

them all in a transaction that took about 30 seconds.
