How Can You Tell How Old a Kerr Mason Jar Is?
Kerr jars were first introduced in 1903, so any Kerr jar you come across will be at least 100 years old. However, there are a few ways to tell how old a specific Kerr jar is.
One way is to look at the logo.
The very first Kerr jars had a simple “K” logo on them. In 1910, the logo was changed to include a star in between the “K” and “E” (for “Kerr Economy”). This star remained on Kerr jars until around 1921 when it was removed.
So, if you see a Kerr jar with a star in the logo, you can be fairly certain it dates from 1910-1921.
Another way to date Kerr jars is by looking at the embossing on the lid. Early lids simply said “Mason’s Patent Nov 30th 1858″, while later lids included other embossings like “Kerr Glass Mfg Co., Los Angeles & San Francisco CA” or “Kerr Self Sealing”.
By comparing the different embossings, you can get a pretty good idea of how old your Kerr jar is.
Finally, you can also use dating sites like Antique Bottle Depot (www.antiquebottledepot.com) which have databases of antique bottles and their approximate age ranges. With a little bit of research, you should be able to accurately date your Kerr Mason jar!
Are Kerr Mason Jars Valuable?
Kerr mason jars are not particularly valuable, but they can be worth a lot of money to the right collector. They were first produced in 1913 by the Kerr Glass Manufacturing Company, and were intended for home canning. The company continued to produce them until 1966.
Today, Kerr mason jars are most often used as decoration or for storage, rather than for canning. They can be found at many antique stores or online. Prices vary depending on the jar’s age, condition and rarity.
Some Kerr mason jars have special value because of their color. Clear jars are the most common, but green, amber and other colors are also collectible. Jars with embossed designs or logos are also of interest to collectors.
If you think you might have a valuable Kerr mason jar, it’s best to consult with an expert before selling it. There are many fake or reproduction jars on the market, so it’s important to get an accurate appraisal before selling your jar(s).
How Do You Tell the Date on a Mason Jar?
Mason jars have been around for over 150 years, so there are a lot of them out there without any markings at all. But if you do find one with markings, here’s how you can date it:
Look for the maker’s mark.
Ball and Kerr are two of the most common brands, but there are many others. If you can find the maker’s mark, that will usually tell you when the jar was made.
Check for a patent date.
Mason jars were first patented in 1858, so if you see a date on the jar, it will be after that. Some jars also have a patent number; if you see a number starting with “RE” or “Pat,” that means the jar was made between 1858 and 1920.
Look for embossed lettering.
Jars made before 1900 will often have letters or initials embossed on them; after 1900, numbers were more common. These letters and numbers can help narrow down the age of the jar quite a bit.
Check the color of the glass.
How Old is a Kerr Self Sealing Mason Jar?
Kerr self sealing mason jars were first introduced in 1913. The Kerr Company was founded in 1855 by Alexander H. Kerr, a glassmaker from New York. He started the company in Philadelphia, but later moved it to Trenton, New Jersey.
Kerr is credited with inventing the screw-top lid that we now use on Mason jars.
The idea for the self-sealing lid came about because of the need for a better way to seal canning jars. At the time, most people used metal lids with rubber gaskets.
These lids did not always create a tight seal, which could lead to food spoilage. Kerr’s self-sealing lid solved this problem by creating an airtight seal that was still easy to open and close.
Today, you can find Kerr self sealing mason jars in two sizes: regular and wide mouth.
The regular size jars are typically used for canning fruits and vegetables, while the wide mouth jars are more popular for jams and jellies. You can also find these jars in different colors, although clear glass is the most common.

In 1909, Kerr moved his operation to Tualatin, Oregon, where he continued to produce fruit jars and other canning supplies.
