First, I am not an avid bottle collector so please excuse any omissions or mistakes I make here. I just got a bottle that has UNION and a shield with clasp hands and the Wm Frank & Sons name on one side, a flag and a cannon on the other. The mold mark stops below the crown. It has quite a few bubbles. The mold mark does not go thru the pontil on the bottom. Has this bottle been reproduced and how can I tell if mine is old. It just does not seem to have a good patina. Also, what might the value be if it is authentic. I have a wax seal Wm Frank quart canning jar and it seems to be of better quality in the glass. Any comments would be appreciated.
