These chips were used at the Barbary Coast Training School in Las Vegas. It was owned by Frank Toti and Jackie Gaughan. "The Gaming Table" says it opened in the 1980's and closed in the 1980's. "The Chip Rack" says these chips date from the 1970's. The Orange one is N1016 and the Purple one is N1018. I have 5 sets of the Orange & Purple chips available for $8.(this includes postage) and 5 more of the Orange chip alone for $4.(this includes postage). If you are interested, please email me or post here. First 10 parties I hear from get them. Thanks. Doug
