The new Flamingo Las Vegas strikes are in play. These are the ones without the word Hilton on them. They have the S mint mark.
Update: Collector King Dinosaur has pointed out that, while the word HILTON has been removed from all of the 2001 strikes, the
design showing both sides of the building still has the large Hilton H logo prominently displayed! Since the Flamingo is no longer a
Hilton, now we have to wonder whether this will get removed, and the strike reissued, like the NHL logo on the Las Vegas Club
hockey strike, or the NY logo on the NYNY Babe Ruth strike.
