A surprising number of common household items are being thrown away every day — and experts say some of them may still have significant value.

From old electronics and unused household equipment to certain documents and collectible items, Americans may be overlooking things that could potentially be recycled, reused or even worth money.

One of the biggest mistakes is throwing away older items simply because they appear outdated.

Collectors and recycling specialists say that certain older household products can become increasingly valuable depending on their condition, rarity and demand.

Experts recommend taking a few minutes to check unfamiliar items before putting them in the trash.

That old box in the garage?
That forgotten electronic device in a drawer?
Those items sitting in storage for years?

They may be worth more than you think.

Before throwing something away, experts recommend checking its model, age and condition — and researching whether there is a market for it.
