While canning jars have been around for a long time, it wasn’t until 1858 that the screw-on lid was created.
Prior to that time, flat tin lids were attached to the jars with wax rings.
Blown glass jars are more valuable than molded ones.
Values of collectible mason jars may range from around $6 to $10 all the way up to hundreds or even thousands of dollars.
Reproductions of some of the most valuable mason jars date back almost 40 years.
