Historical Blown Beer Glasses

I have these two blown green tinted glasses. They are definitely mouth blown because they are very mishapen and asymmetrical. I'm wondering how old they are and if they are worth anything? They are made from what seems to be old glass that is heavy and has bubbles in it. There is a "burn mark" on the side of one of the glasses which I can only imagine is from the blower. You can see from the shadow on the paper that they are very wavy in the glass. I couldn't find a mark or any type of labeling that would help identify them and have searched for hours on the internet for anything similar but haven't found anything. Any help would be greatly appreciated.
