One of the most common emails I receive comes with a description of a jar—e.g., Blue pint Perfect Mason with the number 5 on the bottom—and the question, “How old is my jar?

The jars that I found have what is known as the “triple L”. This site, West Saint Paul Antiques, has wonderful information on dating fruit jars if you would like to find out more about an old jar you may have!
