9 Nearly Worthless Gadgets You're Hanging Onto for Dear Life

You can't put a price on childhood memories, which explains why most of your favorite toys and gadgets from childhood aren't worth squat.

Now, you can still make a nice profit off unopened, exceedingly well-maintained or rare items from your younger days, but the majority of your prized possessions are too new to be artifacts and too old to be useful

Before you try to sell your childhood dreams away, check out the nine items that have much more sentimental value than market value. And if you decide to junk them, think about donating orrecycling.

1. Most of your old sports video games

Madden2 — Madden NFL 2000 might be worth a lot sentimentally, but not much monetarily.

You might treasure the afternoons you wasted away with your friends playing Madden NFL 2000and High Heat Baseball, but the games themselves are almost worthless. According toPriceCharting, which records listing prices for video games on eBay, Amazon and Half.com, most sports games for Nintendo 64 and Playstation all start at about $3.

2. Super Soaker

Nothing said summer like pumping this cumbersome canon until it squealed and subsequently nailing your best friend in the eye. Unfortunately, a used Super Soaker probably won't get you more than $20 on eBay since they're still being made today — albeit with a little less power.

4. Sony Walkman cassette players

Walkmen — Better for pumping out the jams then pumping in cash.

Speaking of obsolete ways to rock out, don't bother trying to sell your Walkman cassette player. If anything, digging up that old copy of Backstreet Boys' "Black & Blue" and finally coming to terms with those grade-school crushes might be more valuable.

Some from the 1970s and '80s can fetch hundreds of dollars in near-mint condition, but the one you rocked in the '90s won't get much more than $25.

5. iMac G3

Yes, they're pretty and colorful, and yes, you can actually get about $150 for one if you manage to sell it. However, that's exceedingly difficult to do on eBay, where listings for the computers get little love with slashed prices.

6. Tamagotchi

These virtual pocket pets might have you caused you (and your teachers) a lot of stress back in the day, but that won't amount to much profit. Tamagotchi are still made today — there's even an app now. By 2010 there were roughly 75 million around the world. Not rare = not too valuable.

7. Casio Calculator Watch

CasioCalcWatch — It's time to stop trying to sell these.

While the calculator watch had a heyday in the 1980s, it's been rendered obsolete by modern inventions, like PDAs, cellphones and fashion. Some modern top-of-the-line models go for a nice price, but the numbers aren't in your favor if you list a standard version. You'll be lucky to get more than $15.

8. Palm Pilots and other PDAs

Another victim of the proliferation of smartphones, PDAs serve little purpose or utility now. And since it hasn't been too long since they were used, there's little nostalgia factor to drive up the price. High-tech models from the past decade may get you $40, but basic and older PDAs barely scratch $20.

9. Boomboxes

With all due respect to Radio Raheem, the boombox's glory days are long gone, and so is any chance you had to make some money off of it. While the boombox carries unique musical and cultural value, that won't translate into cash.

Some rare vintage models will go for $50, but the rest fall somewhere between $15 and $25.
