Question:

Hello,

I spoke to the RWCS office, Friday, about my crock.  I’ve attached pictures.

 Anything you can tell me would be wonderful.

Answer:

Beth, you have a Red Wing safety valve jar (canning jar).  Some of them have a pat. date of May 21, 1896 and they were discontinued around 1920.  They came in 1 gal, 1/2 gal and 1 qt sizes.  In perfect condition with lid, hardware and bottom signed, the value is between $75 & $100.  Al Kohlman
