I was looking over my collection and found a discrepancy. The Flamingo Hilton Las Vegas Feather logo with GDC mintmark is noted by both Marv Weaver and Richard Anderson (with photos) to have both the 1946 and 1996 casino versions and was made in 1999. But neither of these is listed on the Silver Striker Index., although the Bugsy Siegel is listed. Do either or both of these exist? TIA for any info.
