From cell phones to DVD players, e-readers to video game systems, those old electronics sitting in your house could be worth big bucks if you know what to charge and when to sell.
When Varian Johnson started packing up his house for a move, he discovered a treasure trove of old electronics. He'd forgotten all about.

"You get it and you use it and you think you're going to sell it or do something with it or re-purpose it and it kind of gets stuck at the bottom of the drawer and you forget about it," Johnson said.
But experts say it's time to clean out those drawers because old, outdated electronics could easily be turned into gadget gold.
"There's never been a better time to get top dollar for your electronics," said Michael Fridgen, CEO, Decide.com.
Of course some products have more resale value than others. Experts say smart phones, tablets and laptops are all great for resale, with Apple products holding the most value.
"Even an iPhone that's up to 18 months old will get up to 50 percent of it's original value," said Fridgen.
An old Blackberry Curve was worth $75. A used Nintendo Wii could fetch $150. A first generation iPad is still worth around $300.
And while old printers or fax machines don't usually sell for much, experts say old model e-readers can retain much of their value.
"They tend to work for very, very long time. When next year's e-reader comes out, it doesn't stop your old e-reader from being able to read a book," said Michael Flaxman, CEO and Co-Founder, Priceonomics.com.
So how do you know what an item is worth? You can try searching Craigslist, eBay or Amazon to start.
Or a newer site, Priceonomics.com, which analyzes thousands of deals each day to calculate current value.
"We've indexed hundreds of millions of posts. Absolutely anything you might buy on eBay, Craigslist or offline in the real world, we know what it's worth," said Flaxman.
In addition to knowing what to sell, you'll want to consider when to sell.
"If you sell your product before the new version's announced, you can get considerably more money for it," said Fridgen.
Websites like decide.com stay on top of the new release rumors and can help you decide whether to sell or hold.
"Prices are changing at a very fast rate. We see, on a given day, 20 percent of products are seeing a price change," Fridgen said.
If the price is too low, consider donating instead of selling.
"Oftentimes you can get a tax deduction, you'll get that item out of your house, and someone else will be able to start enjoying it," said Flaxman.
As for Johnson, he was surprised to find out his old gadgets could earn him over $700 in cash.
"Very surprised, very surprised by how much it's worth. I think I'm going to sell it," he said.
So where do you go to sell these items? Experts say Craigslist is good for larger items that might cost a lot to ship, whereas eBay instant sale and gazelle.com are great for items like phones. If you're just upgrading, stores like Best Buy or Game Stop will also buy your items -- for credit instead of cash.
