I remember the first time I saw one was at my friend’s house in 1993 and even though by then is was already old, I still thought it looked cool. In 1984, Apple released their original Macintosh to great fanfare. For the exorbitant price of $2,495 (over $5,000 in today’s money), the cute all-in-one computer could be yours. Today, you can buy one for less than that, but you’ll still shell out around $1,000 for one in decent working condition — or more. In 2014, one was sold on eBay for $1,598. And here’s a fun bonus fact: all early Macs have the signatures of the Apple team embossed on the inside of the case.

If you were alive in the 1980s, the Sony Walkman was probably a big part of your life. The first model of this groundbreaking technology was the TPS-L2, and it allowed people to play their own personal soundtrack anywhere and anytime; I bet at least one of your siblings had one of these. They still look cool!. These days, of course, we carry thousands of songs in our pockets, but back then, we had to deal with cassettes. If you’re hoping to go for a more retro sound, working Sony TPS-L2 Walkman models can be found on eBay, but they cost quite a bit. Average asking price is around $350, with some sellers wanting at least $700 for devices in pristine condition.

Here’s a few toys that may be buried in your old closet and worth a lot more than you expect.

1. Transformers Dinobot Swoop: $90 - $1400
2. He-Man action figures: up to $300
3. Star Wars Micro Collection Millennium Falcon: $60 - $300
4. ( a personal favorite) The Real Ghostbusters Proton Pack: up to $500
5. Polly Pocket : up to $500
6. Pokemon Cards: Complete first-edition card sets can cost $4600 to $8700.
7. Magic the Gathering Cards: The Gathering debuted in 1993, and some of the earliest cards produced can fetch several thousand dollars from collectors. A sealed Alpha starter deck has sold for more than $8700, while a single Black Lotus alpha-deck card—one of only 1100 ever printed, considered the “holy grail” of Magic cards—is worth more than $27,000.
