I found all of these today in one yard. The padlock says ROYAL CARRIBBEAN Cruise Lines. One of the cars is a 1980 Mattel Hot Wheels BUZZ OFF. Oh and 29 newer coins, not even a wheat penny
I love finding the cars. I always want to keep them and place them on display but my wife cleans them up and places 5 of them in a bag and sells them at the thrift store she consigns at.
