Hello! I've reccent dug an Ball-blue Half-gallon Mason Jar c.1923-1933 With "Pe ffct" lettering error.
Although I'm quite attached to it.. I was wondering if the error would effect its value in any way. Thanks!
I do a lot of canning and have seen errors like this - at times the molds get filled with material, thus the missing letter during molding. Your jar is about a 12.00 - 18.00 error, perhaps a bit more due to the size.
