About 15 years ago a man who owned a convenience store gave me a large metal, bottle shaped Coca-cola thermometer. It’s 29 inches tall and about 8.5 inches wide. It has a hole in the top of the bottle and one at the bottom for hanging. The thermometer is in great shape and it works, the rest of the bottle is in really good shape as well. At the bottom of the bottle it says “ASSEMBLED IN MEXICO”. Is it worth anything, what year was it made? Any info would be greatly appreciated
