Re: flamingo hilton $25 chip Las Vegas, Nevada
If i'm not mistaking, it is 11th issue, listed in the US Casino chip price guide as R-10, valued $7500 / $12000 / $15000
It says : "picturing 3 small pink flamingos, this chip is unlike any other. Perhaps this was a backup chip used for a short time and then destroyed, or a regular issue chip that was used for such a short time that almost none walked out of the casino. Of the two know exemples, one is cancelled."
Looks like a nice little treasure you found here ! Lovely chip indeed.
