16. Mason Jars
You can go to any Walmart in the country and buy a 10 pack of Mason Jars for $10. So what makes one worth $1, and another worth $1,000? The Mason company was founded in Vineland, New Jersey in 1858. This area is famous for its glass blowing experts, and a tinsmith named John Landis Mason invented the screw-on top. Ever since then, the world has used his jars for canning air-tight fruits and vegetables to help them store food for the winter.
Sometimes, antique niches are localized. Something that’s worth almost nothing in one area of the country can fetch a lot more somewhere else. I live in southern New Jersey, so it’s actually very common to find antique Mason jars here. Antique dealers will take them to far-away antique shows, and make a lot more money selling them elsewhere. One of the most valuable mason jars were used for dispensers, and they go for about $1,000 each.
