I happened to be have been born on Leap Year Day. I currently have three different chips for Leap Year Day: CG086522 $5.00 from the Riviera dated 2004, CG057850 $5.00 from Four Queens (year not marked), and CG158096 $25.00 from Morongo dated 2016. Anyone know of any others? And if so, does anyone have one they'd like to part with?
