If you were like me, you’ve probably got boxes in the attic or tucks under the bed where you stored childhood treasures—things you forgot existed.
What’s wild is how many of those relics are now quietly worth real money. The collectibles market is projected to grow significantly over the coming years, with some categories seeing particularly strong demand.
So if you’re curious, I’ve pulled together items I found in old storage that surprised me—and helped me realize how many “lost” collectibles you might have laying around.
First-edition comic books
Back when I was a kid I grabbed a few old comics, flipped through them a few times and stashed them away. It wasn’t for investment—I just liked the stories. Now, well-preserved comics from certain eras and publishers are attracting serious collectors. Condition, rarity, and popularity of characters matter.
If you find one with minimal wear, no missing pages and a big name on the cover, you might be sitting on something more than nostalgia value. I found one that nearly tripled in price compared to what I assumed it was worth.
Vintage trading cards
You probably had baseball cards or those monster collector cards as a kid. Many folks dismissed them as junk. But serious trading-card markets are booming—sports cards, game cards, and some pop-culture sets are now treated as investments.
Dig through old boxes and look for sealed packs, cards in near-mint condition or ones featuring iconic players. It’s less about the whole stack and more about the standout pieces. You might find a card you grabbed with no thought now fetching way more than what you paid.
Limited-run toys and action figures
That toy you bought when you were six and kept in the box? Some of those are now hot items. Figures from certain manufacturers, franchises, and limited editions often command big prices. The market for nostalgia-driven items is strong.
Look for ones still in original packaging, without damage, and check manufacturing runs or special versions. The ones you “almost threw away” might actually be collectors’ treasures. I found several boxed toys that now deserve a second look.
First-run vinyl records
If you ever picked up records, albums with early pressings or special artwork can surprise you. Music memorabilia is a niche that continues to appreciate. A first-pressing of a big album with original artwork or limited release colors can leap in value because the supply shrinks over time.
Go through your record rack, check for “first pressing,” “original print,” or unique labels. I unearthed one record I assumed was common—turned out it was a rare version with a market value I wouldn’t have predicted.
Vintage coins and currency
Coins and bills from older eras often sit in drawers overlooked. But numismatic items—especially those with low minting, historical context or unique errors—are sought after. Rare coins are making their way into alternative-asset portfolios.
Dig up old change jars or bills kept for “becoming antiques.” Even if the face value isn’t impressive, the collectible value might be. I found a coin with an unusual error and a surprisingly high value when graded and listed.
Original game consoles and cartridges
If you held onto a console you rarely used, or cartridges from the early days of gaming, you may want to check again. Retro gaming gear is in demand. Early consoles that launched first in a region, limited editions, or bundled with rare games now sell for far more than their original price.
Inspect for consoles in working condition (or at least complete units), find original packaging if possible, and research what models are in rarity. A dusty old console I found in the garage turned out to be a special edition and spun heads when I listed it.
Signed books or first editions
If you kept books from your youth—or bought special editions—there may be hidden value in first-editions, especially if the author later became prominent. A book signed or inscribed by an author can attract serious interest from collectors.
Check the copyright page for first printing details, look for signatures or inscriptions, and assess condition. I found one signed copy tucked away that brought in 10-times more than generic thrift-store books.
Rare posters or movie memorabilia
Posters from movies, concerts or events you once attended sometimes vanish over time, which pushes up value for originals. A legitimate poster from a notable first run, especially in good condition, can fetch more than you might expect.
Honestly, I didn’t expect the poster I grabbed for free in college to go for much—but once I researched, its edition number and condition made a difference. If you find one rolled (not folded), minimal creases or fading, you might have something.
Limited-edition sneakers or streetwear drops
If you held off tossing those old “drop” shoes or limited-edition brand items, you may have done well. The market for certain sneakers and streetwear has exploded, driven by scarcity and cultural demand. Some pieces originally bought for a few dollars now carry huge resale prices.
Look for original boxes, tags, limited-edition labels, or collaboration pieces. Even if your pair is gently used, there may be value. I found one pair I wore little and it brought more interest than I expected.
Fine art prints or lithographs
If you bought an art print from a student or local gallery years ago, it’s worth checking: some mid-century prints or limited-edition lithographs are now collecting interest. The art and collectibles space is seeing steady growth and prints with recognized artists or studio runs are gaining traction.
Check for edition numbers, signatures, and condition. While it won’t always make you wealthy, the piece you under-estimated might have appreciated. I discovered a print I had framed decades ago now listed significantly above what I assumed was its value.
