This is a very unusual jar in the fact the "PFRFECT & MASON" are both in a sort of slug plate. Very boldly embossed "PFRFECT MASON" I have never seen another Perfect mason jar like this one. Of course I have seen quite a few with this error embossing I haven't seen the slug plate or mold line's as you see in this jar. Highly unusual. Circa:1920's

  An early 3L loop Ball Standard from around 1900 or a bit before. This jar is spelled "STANDAPD" Redbook #314-2

  A quart Ball blue Sure Seal jar with an error in the date this jar isn't found too often with the Lightning dimple neck version and this one also has an error in 1908 which reads 1988 instead. You can click the icon below to see a closeup view of the date.

  I have found quite a few error jars but this is the first offset Perfect mason error jar I have run across. Embossed "PFRFECT" in Ball blue of course.

  This jar is an early Sure Seal jar with the large patent date embossed on the front. Usually if found these jars have smaller letter's in the date than the one you see here. This particular jar also has the bulge neck as you can see in the pic which also adds to it's unusual style. The error on this jar is in the patent date. If you look at the word "July" you will notice it has a backward "J" in July.  Circa:1911-1916

  This jar was made by the Ball brother's as they made product jars for customer's as well as their fruit jars. Embossed "The Haserot Conpany Mason Patent" you can see Company is misspelled and says "CONPANY" instead of Company. Circa:1900-1910

  This jar here has a couple things going for it as it isn't your normal Perfect Mason. Notice the word Perfect is spelled "PEREFCT". Also if you will look at the mouth of this jar you will see that it is uneven. This is called a fluted lip. Ball made these this way so only a 1 piece zinc lid would seal on the beaded neck and consumers wouldn't go buy another brand 2 piece lid. Since it is uneven the 2 piece lid will not seal on the very top so you have to use a zinc cap with rubber seal on the beaded neck. Circa:1915-1923

  This has always been an error jar I liked a lot. I used to have one of these and sold it awhile back and wish I didn't. Recently I found another so I have one back in the collection. Quart in size and Ball blue this is a Ball mason with the "S" in mason being backwards. Listed as a 3L jar this example is more of a ghosted 3L as it's not embossed really strong on the L. Circa:1900-1910

  I bought this jar probably 20 years ago in a local antique store that's gone now. Embossed "Ball | |ason's Patent Nov 80TH 1858" You notice that the letter "M" is missing the 2 slanted connecting lines so it looks just like I typed it. The big thing is the date which says 80 instead of 30. Quart in size this jar dates from the mid 1890's.

  Here is a neat old jar with the Improved type closure. Light green in color with a Ball brother's glass insert you will notice it also has an upside down "N" in the word Patent. There is also an old piece of tape on the side of it with "Soy 1933" I guess someone's Grandmother was canning with this jar maybe back in 1933. Blown by the Ball brother's back in the 1880's these jars are not real hard to find but not all that common either. I like the screw band glass insert jars and especially in the hg size. First one I have come across with a backward "N" and it's a keeper... 

  This picture has 2 jars in it with the jar to the right being the error jar. A pair of wax sealers that were dropped from the line in 1912. The jar on the right has the entire word Balll ghosted. This is the only one of these I have seen. You don't normally find a Balll Standard with an error but they are out there as in this example.
