Old Microphones
As high as $9,999
While it’s unlikely to be lying around the average home, if you happen to have an old microphone, you could earn yourself a small fortune. Rare pieces, such as the 1940s Neumann U-47, can be worth thousands of dollars.

In fact, a Neumann sold on eBay not too long ago for a whopping $9,999! Granted, it was in good condition – and a battered one won’t get you nearly as much – but it’s worth keeping an eye out for them in garage sales.
