I have two apparently different $.50 Chips from the Ocean's Eleven Casino in Oceanside,CA.

They both appear to be in excellent condition with no apparent wear. One has a GOLD Hot stamp...the other has a Silver.

There is only one listed in Armin's new CA Book.

Does anyone know if this is a variation, error, or is it possible that the "gold" somehow faded to silver? They both have an almost perfect hot stamp.
