3. Ball Mason Jars
Patented and produced by Landis Mason in the mid-to-late 19th century, mason jars were made in all sort of colors, with blue and clear being the most prevalent. Because of their ubiquity, finding Ball jars that are pink, purple, green or amber is much more of a challenge, resulting in them being worth far more than their blue or clear counterparts. If you find a vintage olive green Ball jar or it’s wire carrier in your attic, know that it could be worth $400-500!
Similarly, if you find an upside-down Ball mason jar, then you’re really in luck and need to thank your grandmother…they were only produced between 1900-1910 and can be worth up to $1000 since they’re so rare!
