Most people walk into a Goodwill, Salvation Army, or local thrift shop and see a bunch of used stuff. And yeah, 95% of it is exactly that — someone else’s castoffs. But mixed in with the faded bath towels and chipped coffee mugs are items that people routinely sell for hundreds, thousands, and sometimes tens of thousands of dollars. It happens constantly. The trick is knowing what to look for so you’re not just wandering the aisles hoping to get lucky.
I’m not talking about some once-in-a-lifetime miracle. I’m talking about categories of stuff that are consistently underpriced at thrift stores because the volunteers pricing them don’t know what they have. Here are ten things actually worth hunting for the next time you stop in.
1. Vintage Pyrex
If you take away one thing from this article, let it be this: always check the Pyrex. Those colorful mixing bowls and casserole dishes from the 1950s and 60s have a rabid collector base, and certain patterns go for serious money. The Pink Amish Butterprint set can be worth around $700. A Duchess casserole from 1959 — pale pink with gold flowers — has sold for as much as $3,000 on eBay. Even common patterns in good shape sell for $30-$80 per piece. You’re looking for the older stuff made with borosilicate glass (heavier, more heat-resistant) before Corning sold the brand in 1998. Flip it over, check the pattern, and look it up on your phone before you put it back. A site like Pyrex Love can help you ID patterns fast.
2. Cast Iron Cookware
A new Lodge cast iron skillet runs about $25-$40 at Walmart or Target. But the older stuff — Griswold, Wagner, early Lodge — commands way more from collectors. A Griswold #8 skillet in good condition can sell for $150-$300+. Thrift stores usually price cast iron between $5-$15 regardless of the brand, because it all looks like heavy old black pans to whoever’s tagging them. Even if it’s rusty and crusty, cast iron is basically indestructible. You can strip it down to bare metal with oven cleaner and re-season it. Check the bottom for maker’s marks. If it’s smooth on the cooking surface (not pebbly like modern Lodge), it’s likely older and worth researching.
3. First Edition Books
This one takes a little homework, but the payoff can be huge. Thrift stores price almost every hardcover between $1 and $4. Meanwhile, first editions of popular books — Stephen King, Cormac McCarthy, Harry Potter — can be worth hundreds or thousands. The key is checking the copyright page. You want a first edition, first printing. Different publishers indicate this differently, but the most common method is a number line: if it still has a “1” in the sequence, that’s usually a first printing. An original dust jacket in good condition matters a lot too. A signed Stephen King first edition found for $2 could be worth over $500. Keep your phone handy and search titles that look promising on sites like AbeBooks or eBay sold listings.
4. Vintage Vinyl Records
Most thrift store records are scratched-up copies of Herb Alpert and Barbara Streisand’s greatest hits. But scattered in those bins are original pressings worth real money. A first pressing of The Beatles’ White Album — the ones with low serial numbers — can sell for $500+. Original Led Zeppelin, Pink Floyd, and Miles Davis pressings routinely go for $100-$300. The trick is learning to read the matrix numbers etched into the dead wax (the smooth area near the label). Those codes tell you if it’s a first pressing or a later reissue. The Discogs app is free and lets you identify pressings by those numbers. Check condition carefully — warps and deep scratches kill value.
5. Designer Clothing and Handbags
This is the category most resellers already know about, but it’s still worth mentioning because stuff slips through all the time. Hermès scarves, Chanel jackets, Gucci loafers, vintage Levi’s 501s — they show up at thrift stores and get priced at $5-$15 because nobody on staff recognized them. One reseller found a vintage Hermès Kelly bag for $10 that was later valued at over $8,000. Pro tip from resellers who do this full-time: hit thrift stores in wealthier zip codes. The donations tend to be higher quality. Check labels, check stitching, and learn a few telltale signs of authentic luxury brands versus knockoffs. Poshmark and The RealReal are good places to check comparable sold prices.
6. Vintage Toys and Action Figures
Star Wars figures from the late 1970s and early 1980s are the gold standard here. A vintage Boba Fett action figure — original retail price of $2 — sold at auction for $27,000 in 2015. Luke Skywalker figures have gone for $2,000 to $25,000 depending on condition and packaging. But it’s not just Star Wars. Old Hot Wheels (especially redline models from the late 60s and 70s) sell for $200-$400+. Original Cabbage Patch Kids, especially rare editions, go for around $300. In March 2024, a sealed vintage Lego set found inside a donated jewelry box at a Goodwill sold for $18,000 because it included a rare 14-karat gold Bionicle mask. Check toy bins and don’t skip the board game shelves — pop culture and TV-themed games from the 70s and 80s have followings too. Just make sure all the pieces are there.
7. Paintings and Frames
Two things to look for here, and one of them surprises people: the frame itself. Vintage frames — ornate, solid wood, gilded — can be worth $50-$200+ even if the art inside is terrible. Thrift stores price framed art at $3-$10 usually based on size, ignoring the frame entirely. An 81-year-old former antiques dealer bought a painting for $3 at a South Carolina Goodwill because he liked the 19th-century frame. The painting turned out to be a 17th-century Flemish work. Meanwhile, a Richmond, VA shopper grabbed a glass vase at Goodwill for $3.99 that turned out to be a rare 1947 Murano glass piece by architect Carlo Scarpa. It sold at auction for $107,100. You don’t need to be an art history major — just learn to spot quality materials and craftsmanship.
8. Sterling Silver Flatware
Most thrift store silverware is stainless steel junk worth nothing. But mixed in, every now and then, is actual sterling silver. Look on the back of spoons, forks, and knives for “925,” “Sterling,” or a lion hallmark (British sterling). Thrift stores almost never sort for this. A single sterling silver fork can be worth $20-$40 just in melt value, and full place settings from brands like Gorham, Tiffany, or Reed & Barton sell for hundreds. Carry a small magnet — sterling silver isn’t magnetic. If a spoon sticks to the magnet, it’s not silver. This is a numbers game; check every time you visit and eventually you’ll hit.
9. Jewelry (Real Stuff Hiding in the Costume Bin)
Thrift stores dump all donated jewelry together regardless of value. That means a 14-karat gold chain might be sitting in the same dish as a plastic bead necklace. Look for stamps inside rings and on clasps: “14K,” “18K,” “750,” “925,” “Pt” for platinum. A woman bought a ring at a junk sale for about $13, wore it for decades doing chores, and eventually discovered it was a 26-carat diamond cut in the 1800s — worth around $455,000. That’s extreme, obviously. But finding a $200 gold bracelet priced at $2.99? That happens all the time. Bring a jeweler’s loupe (about $8 on Amazon) and check everything. Even some costume jewelry from brands like Trifari, Miriam Haskell, and Weiss is worth $50-$200 to collectors.
10. Depression Glass and Jadeite
Depression glass — the pastel-colored, slightly translucent glassware made cheaply in the 1920s and 1930s — is now extremely collectible. Pink, green, and cobalt blue pieces sell well, and rare patterns or complete sets can be worth hundreds. Jadeite, that distinctive seafoam green kitchenware, is having a huge moment thanks to Instagram and home decor trends. Look for marks on the bottom from McKee, Jeanette, or Fire-King — those are the most valuable brands. Iridescent carnival glass is another one worth checking. These pieces usually end up in the glassware section priced at $1-$5 each. A single Fire-King jadeite mug in the right pattern sells for $30-$80 on eBay.
How To Actually Do This Without Wasting Your Time
Here’s the thing — you can’t just stroll into Goodwill once and expect to walk out rich. People who consistently find good stuff do a few things differently. They visit frequently, because inventory changes daily. They focus on two or three categories and learn those categories well rather than trying to know everything about everything. And they always have their phone ready to check sold listings on eBay (filter by “sold items” — asking prices mean nothing).
Platforms like WorthPoint give access to over 900 million historical sale prices and 200,000+ maker’s marks, which is helpful when you’re staring at a piece of pottery and have no idea what it is. A subscription costs about $30/month, which pays for itself fast if you’re serious about reselling.
The other underrated move: go early on restock days. Ask staff when new items hit the floor — most stores have a rotation. Tuesday morning at your local Goodwill might look completely different than Saturday afternoon.
You don’t need to turn this into a full-time hustle. Even casual thrifters who know what to look for pick up a few hundred extra bucks a year. And occasionally, someone pulls a $3.99 vase off a shelf that turns into $107,000. Those stories are real. You just have to know what you’re looking at.
