Harvey's and Harrah's experienced counterfeit $100-$500 brass in 1996 and notified all the casinos that they no longer could honor brass chips and removed all of them from play...EXCEPT the yellow Harrah's 1971 dollar which was needed in Tahoe when they were short dollar chips after Bud Jones issues did not work out. Those also disappeared last year.....All that is left in Brass are the Hyatt Regency, Tahoe and the Silver Smith in Wendover. Mel
