Have not seen any of these ,but am pretty sure it is not rare if i have one [] .If you go to -Land of Marbles - they have many new printed ones as well as old matbles for sale and all things marble related ,some really neat stuff .Have not seen these for sale ,maybe some of the Coke collectors have ?
Not sure Mike ,Coke had many promotional items.,Marbles came in cellophane in cereal ,bags with soda six packs ( not sure if Coke was one or not ?), and other products, but have not seen this one .
