The Hershey Creamery is in no way connected to the Hershey candy family !! The Hershey Creamery made ice cream, ice milk, frozen yogurt ect !! There have been several lawsuits between the two companies !! As to value,, I know you can look through ebay and see ridiculous prices,,,but you do not see any bids or sales do you ??
These old milk cans are not exactly in the collectors realm due to the size !! Who would be most likely to want the can would be someone connected to the company or creamery !! Here in my area you can buy milk cans from various dairies for $20. !!~ Since yours has the name of a creamery and if you are in that area, I would say yours might bring &50. to $75. on a good day !! They are nice to have but hard to sell !!
