Whatever book you have...I must get. Imagine having a citron jar..........Ok, as you know there are many variations so it might take a little while but I found one so far. The (keystone in circle)Mason -ground lip, shoulder seal. Thats the first one I looked for because I like it best (but it might not be the most valuable one). QT Aqua $10-12
This jar also comes in Citron($750+)
Olive Green($1000+)
Amber ($750+)
Clear ($200+)

Red Book number 11- The collectors guide to Old Fruit Jars. Take my advice and if you want this book you should find the authors website. He will sell it to you for about 40 bucks. He ships quickly and he threw his autograph on it for me too. If you try to get it off eBay or another third party they will try to rip you off! (I saw some for 100-200 dollars). The NCL jar is 20-30 in Aqua. Once again the values go waaay up for other colors. It's rare in clear-Midget pint size 750-1000 dollarsI think I've only seen an amber shard of a jar once! Thanks a lot for taking the time to look those up for me. I'm thinking about all the jars I've left behind....I'll look up more tomorrow. It's time for bed for me!
Last jar to be identified is the Mason's Patent Nov 30th 1858 (reverse CFJ co). I'm having trouble. What's on the base? There are so many molds.

I'm 90% sure this last jar is 1927-4 which lists for 6-8 dollars. Unless I'm missing something. Lots of variations on this mold which include embossed dots, misplaced commas, and 1's that look like sevens(plus more). Generally the qt sizes in Aqua for this mold don't go for more than 20 dollars(with the lid).
