There are a few fakes out there one was from the Mint an another Frank Sinatra ashtray was faked .yes the prices have dumped the ashtray Pam has in her post I listed on ebay for 150.00 and did not get a bid . I currently sell 50 different Nevada casino ashtray for $50. Sold a few hundred last time I was in Nevada . What won't bring a dollar on the net antique stores in Reno still sell for 10-20 dollars .It's people reliving their past remembering their wedding night at the MGM there not collectors and are just buying for the past.
That said my wife has 2700 different Nevada trays and is still looking for ones she's missing .
