We don’t often think about the value of random thing we have in stuffed away in boxes. However, tons of old items — including things you might own — could be worth a hundreds or even thousands if you bring them to the right place.

Here are some of the most valuable antiques you might find.

1. Paintings

You might not have the Mona Lisa, but you never know if you have a valuable painting in your possession. Some people have said that they lived by painters who gifted them a piece of artwork that later became valuable when the painter struck fame. Worth looking into if you have any paintings.

2. Guitars

Guitars are not only musical instruments, but some consider them pieces of art. They don’t have to be antique, either. Guitars in good condition — even those from the 60’s and 70’s — can be worth a lot.

3. Tools

Head over to your shed or workbench and take a look at your tools. See anything that’s quite old? Older tools can be worth a lot, but you’ll want to check out a price guide to get a more accurate estimate of their value.

If you find anything valuable, you could sell it and have enough money to buy a brand new tool set.

4. Persian Rugs

Persian rugs take a long time to appreciate in value, but the wait is worth it if it’s been in your possession for decades. Rugs over 100 years old are considered antiques. Price is determined by factors such as size, material, and design.

5. Books

Did your grandparents or great grandparents buy a well-known book when it came out decades ago? First edition books from the 1930s - 1950s (and before) can be worth thousands of dollars.

6. Baseball Cards

In general, baseball cards increase in value as they get older. That being said, there are several other aspects that play into the card’s value. If you have baseball cards, consider getting them appraised.

7. Lamps

If you’ve inherited an old lamp that just doesn’t seem to fit your current decor, don’t fret — depending on brand, an old lamp could earn you thousands, if not tens of thousands of dollars. Brands like Handel and Pairpoint will net you a pretty penny.

8. Christmas Ornaments

New Christmas ornaments are a dime a dozen, but older Christmas ornaments passed down through generations could be worth a lot. A single ornament could be worth several hundred dollars; not bad for a little orb you hang on a tree once a year.

9. Silverware

Believe it or not, old sterling silverware can net you a good amount of cash. Individual pieces can fetch you a few hundred — but if you have a whole set, that’s potentially a couple thousand dollars.

10. Vintage Ads

Vintage-style ads add a touch of fashion to your home when placed well. However, real vintage ads may be worth selling instead. Even ads for the most mundane items could fetch your hundreds.
