The most valuable blue-tinted mason jars are typically those produced by Ball, Kerr, and Atlas, particularly from the late 19th to early 20th century. Jars in the "Ball Perfect Mason" series and those with unique features, such as rare sizes or embossing, tend to fetch higher prices among collectors. The value can also increase based on condition, rarity, and historical significance. Antique jars in pristine condition can sell for hundreds to thousands of dollars at auctions or collector shows.

If it is a blue glass jar than it is an old one. They used those jars to store many things from foods to poisons during the civil war. Also, check the lid if it has one. Metallic lids were used on the older mason jars. I have also heard that if the jar doesn't have a seam going down the side of it, it is one of the oldest models that mason produced. They hand blew jars before machine glassing them.
