i looked for these on the web today, couldnt seem to find out if they have any value or not. Grandma bought the 6-pack for me when i was 7 i think, sometime in the 70's i know for sure. i drank them and she saved the cans, except for a few scratches they are in excellent shape. dug them out of her "dungeon" this weekend. any idea of what they may be worth?
