Blue Mason Jars do not 'turn' blue, they are manufactured from a greenish/bluish glass.
This glass contains trace amounts of Iron and/or Cobalt ... the greater the concentration, the deeper the color.

Which mason jars are worth more than average?
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.
