hi this is matt again does anyone know the value of this mason jar I found at my aunt's estate
it says lockport mason improved on the mason jar and is 4 & 1/2 inches tall and 2 1/2 inches across the top .
Can't tell you much about the jar, but that looks like a zink top. Inside is there a porcilcin insert just under the cap? A rubber seal was added, and used for canning.. I never liked those caps.. To hard to tell if you had a good seal..
