Sometimes you can find a jar that has a word misspelled and mishaps like this make the jar rarer and add to the value.There are a variety of closures for canning jars from the tin lids to the modern screw on lids.If you can your own fruits and vegetables, you might be surprised to find that the value of old canning jars is often significant.If you are using the ones your grandmother left you, that jar of spiced peaches might be worth more than you think.When a jar is found with its original closure, it will be more valuable than when it isn't.A number of factors go into the final value of a canning jar.Thousands of canning jars were embossed with the Mason patent date, November 30, 1858.
Jars actually were embossed with this for over 50 years so the embossing in itself should not be the sole criteria for determining date and value.
An embossed design that is unusual or unique will fetch more than the 1858 embossing on a jar.
Prior to that time, flat tin lids were attached to the jars with wax rings.
John Mason was a tinsmith in New York and perfected a machine that would cut threads into the lids, creating a jar with a reusable, screw-on lid.
Collecting canning jars got its start in the 1960s with a renewed interest in canning and other domestic arts.
While canning jars have been around for a long time, it wasn't until 1858 that the screw-on lid was created.
