This is an old Ball Mason jar in a wire holder. I believe this jar to be pre 1923 based on the upward and underlined script of the Ball logo. The under line has the double loop and the letter “a” in the word “Ball” has the front leg. The cap is zinc with white ceramic insert. There are some inconsequential bubbles in the glass. That is another indication of age. The vintage wire holder has some rust on the wire.
This old mason jar in its holder would make a nice decoration or use it to store pasta, beans, etc.
