This is the Pearl & Chrome series, also known as Palukuro, released for Hot Wheels' 56th anniversary. The colors are turquoise (blue-green) and copper (copper plating). The models are the following five: 1/5 TOONO" 83 CHEVY" SILVERADO 2/5 TOYOTA LAND CRUISER 3/5 '21 FORD BRONCO 4/5 '65 MERCURY COMET CYCLONE 5/5 CUSTOM 70 HONDA N600 These are mass-produced items. The cardbacks don't have major damage and are in relatively good condition, I think. These sets are becoming hard to find, so take this opportunity. Silverado, Land Cruiser 40, 47, Land Cruiser, Bronco, Mercury Comet
