Most Ball mason jars which have an aquamarine bluish tint to them carry little to no collector's value at all, according to Glass Bottle Marks, because they are not actually rare. The Ball company created hundreds of millions of jars between 1913 and 1960. The color is called "Ball Blue."
Due to hype concerning the jars, the Ball company resumed production of the blue jars in 2013 with the introduction of the "American Heritage Collection." Production of a limited-edition set is scheduled to continue between 2013 and 2015; this set has thinner glass, smaller volumes and a lighter blue tint than the original jars.
