how much is a octagon shaped canning jar worth, no chips
How old is a green ball ideal canning jar with a wire clamp and number 7 on the bottom? Without seeing the jar it is difficult to determine the age of the jar. Ball has been making canning jars since 1886 and the wire clamp was one of the earliest mechanisms used to close the jars. The number on the bottom is most likely represents the mold number and may not have any bearing on the age. A collector would need to see the jar to determine a more exact age, since there are other markings that could be used to identify approximately when it was made. So, the green ball ideal canning jar with a wire clamp and number 7 on the bottom could more than 100 years old.

Any Ball (Atlas or Mason) canning jar that is not a screw top is a collectible. These are no longer produced for canning. They had glass dome tops that were held down by a wire lever, and sealed with a gum-rubber sealing ring. Some screw top canning jars may be collectible items if they are no longer manufactured, or were manufactured by a company no longer in business. I still use my Atlas jars.
A Mason or canning jar.
