I have been trying to get this chip comfirmed to a casino but it is driving me crazy. The shield hot stamp on the Large crown is very similar to the Wilbur Clark Monte Carlo Shield. The WC below the $25 is the same style used on the $5 ElRancho N6714. There is a $25 White N6715 Large Crown with $25 WC BUT it has ElRancho on the obverse. Is this a new Wilbur Clark chip? and if so which of his casinos was it used at
