4. Antique Frames
We often hear stories about paintings that made their owners rich overnight, but what many people don't know is that the frames could also be very valuable. Even if you hate a painting, take a closer look at its frame because certain ornate antique borders are worth more than the artwork itself. Back in 2012, one woman auctioned off a $9.99 painting she bought from Goodwill for $27,000.
The iconic low-thermal-expansion borosilicate dishware is still being manufactured, but if you can get your hands on dishes made prior to 1998 you could net some extra cash. An original Pyrex dish could sell for up to $3,000, depending on the color and design.
Utensils made out of real silver are still a hot commodity, so next time you're at a thrift shop or garage sale, don't ignore the cutlery. They may look really old, but that's nothing a little baking soda and water can't fix. To make sure you're not being duped, tap on a piece of silverware, if it rings then it's the real deal. Keep your eyes peeled for coveted high-end brands like Tiffany if you want to increase your item's worth.
7. Vintage Canning Jars
Before these jars became trendy for their multi-purpose, they were used for storing and preserving food. These vintage canning jars were a household staple from the 1840s to 1920s before refrigerators were invented. If you can get your hands on an original canning jar, you could make up to $1,000. Look out for popular brands like Ball, Violet, Willoughby and Hero.
