My cousin found a bunch of bottles and jars while working on an old home. He knows I collect bottles so he asked if I could give him some info on the stuff. He's mostly curious about the age of some of it. Im not really into jars so can anyone on here help me out and tell me a little about these. Are they pretty common? Age? Do they have any value? One thing he also wondered is if the lid on the French's is the original lid. The Jumbo has a Ball mason lid on it so Im pretty sure that ones not original. Thanks a lot for any info you can give me.
