1. Vintage Jewelry Boxes

People often leave behind old jewelry boxes because they see them as “just storage.” What they don’t realize is that these boxes, especially mid-century or hand-painted ones, can hold real collectible value. Dealers know that even minor markings or craftsmanship details can make a box worth far more than its surface appearance suggests. Some boxes also carry provenance or branding that collectors hunt for, which can drive up their appeal.
The materials used matter, too. Mahogany, cedar, and certain inlaid woods are especially prized for their durability and finish. Even a slightly cracked or worn box can be restored, giving it a second life in a collector’s home. Dealers often circle back to estate sales specifically for these, knowing they can flip them for significant profit.
2. Old Silverware Sets

Estate owners often overlook silverware sets if they’re tarnished or missing a few pieces. Dealers, however, recognize that sterling silver patterns from certain makers are highly collectible. Even partial sets can fetch good money, especially if they come from companies like Towle or Gorham. The craftsmanship and design patterns often dictate the value more than completeness.
Silverware is surprisingly resilient, too. Tarnish is easy to remove, and individual pieces can be sold separately if the pattern is desirable. Collectors also appreciate antique serving pieces like ladles or sugar tongs. For dealers, a discarded silver set is often a small goldmine waiting to be polished and sold.
3. Porcelain Figurines

Porcelain figurines often get overlooked because people associate them with kitschy décor. Yet many figurines, especially those from Lladro, Hummel, or Royal Doulton, have serious collector appeal. Dealers look for subtle details: markings on the base, the artist’s signature, and the condition of delicate features like hands or faces. Even a chipped piece can have value if it’s rare enough.
These figurines are deceptively intricate. The hand-painting process, the material quality, and the production era can all drive up demand. Seasonal or themed collections are particularly attractive to collectors. Estate sale shoppers who ignore these pieces leave potential treasures behind every time.
4. Rare Books

Old books get left behind if they’re dusty, falling apart, or not recognized as first editions. Dealers know that first editions, signed copies, or books from specific print runs can be worth hundreds or even thousands. Even less “literary” works can carry value if they’re early prints of popular titles or niche topics. Collectors often hunt for these hidden gems at estate sales.
Condition matters, but so does rarity. A slightly worn dust jacket won’t necessarily ruin a book’s collectible value. Provenance can add even more appeal if a book belonged to a notable person or came from a unique library. Dealers often circle back specifically for the rare or unusual volumes that regular buyers walk past.
5. Mid-Century Modern Furniture

It’s common for people to leave behind mid-century modern furniture if it doesn’t match their current décor. But dealers know that pieces by designers like George Nelson, Eames, or Knoll can command high prices. Even unbranded or lesser-known pieces from the era are often sought for their aesthetic and structural quality. Estate sales are one of the few places to find these in person.
The materials and construction are key. Solid wood, teak veneers, and metal accents all matter, as do original hardware and joinery. Scratches and wear are often seen as character, not flaws. Dealers often return to sales once they hear that certain furniture pieces have been overlooked.
6. Vintage Cameras

Old cameras frequently get left on shelves because people assume digital cameras are all that matters now. Yet film cameras, especially those from brands like Leica, Rolleiflex, or Nikon, are highly collectible. Dealers know the difference between a cheap plastic camera and a model that has historic or professional appeal. Even lenses and accessories can add value.
Cameras are attractive because of their nostalgia and technical quality. Film enthusiasts and collectors hunt for functional models and rare bodies. Accessories like tripods, flashes, or lens cases often increase a lot of value. A camera left behind at an estate sale is often snapped up quickly when a dealer realizes its potential.
7. Vintage Board Games

People sometimes toss old board games thinking they’re just outdated or incomplete. Dealers recognize that vintage games, especially those from the 1950s–1980s, can be collectible, particularly if all the pieces or original boxes remain. Limited editions or first prints of games like Monopoly, Clue, or even obscure European titles are surprisingly valuable. Collectors often look for nostalgia plus rarity.
The box artwork can drive the price just as much as the game itself. Colorful, intact packaging appeals to both collectors and décor buyers. Missing pieces aren’t always a dealbreaker; replacement parts are available for popular games. Dealers often circle back to estates where these games are left in dusty corners.
8. Costume Jewelry

Costume jewelry often gets left behind because people consider it cheap or outdated. Dealers, however, know that brands like Trifari, Weiss, or Coro are collectible, especially vintage mid-century pieces. Even items with minor wear or missing stones can fetch money when cleaned and restored. The appeal is both for fashion collectors and resale markets.
Materials and design make all the difference. Unique rhinestone arrangements, signature clasps, and early plastics like Bakelite are highly sought. Costume jewelry can also complement current fashion trends. Estate sales regularly leave these treasures behind for savvy dealers to pick up later.
9. Glassware and Crystal

Plain-looking glasses often get ignored at estate sales. Dealers are on the lookout for high-quality crystal or hand-blown glass, especially from makers like Waterford, Baccarat, or Murano. Even small imperfections don’t always ruin the collectible value. Some patterns are discontinued and highly sought after by collectors.
Glassware is deceptively tricky to value, which is why dealers are key. They know which patterns, colors, and cuts are rare. Stemware, decanters, and serving bowls can all fetch surprising amounts. Many estate sale visitors simply don’t recognize the difference between ordinary glass and collectible crystal.
10. Antique Tools

Old tools get left behind because people assume they’re outdated or broken. Dealers know that hand tools, especially branded ones like Stanley, Lie-Nielsen, or vintage woodworking planes, are highly collectible. Even rusty or worn tools can be restored and sold for a premium. Certain tool types, like early measuring devices or cast iron items, have niche but dedicated buyers.
The craftsmanship and brand history matter. Tools made before mass production often have better steel and construction. They also appeal to both collectors and practical users who want quality tools. Dealers often keep a mental list of estates that consistently have overlooked tools.
11. Vintage Vinyl Records

Vinyl has made a huge comeback, but many estate owners still leave records behind. Dealers are hunting for first pressings, rare albums, and records in good condition. Labels like Blue Note, Motown, and original rock pressings are highly desirable. Even incomplete collections can be broken up for valuable individual albums.
Condition is everything in the vinyl world. Scratches, warping, and jacket condition all affect value. But rare releases or limited pressings can offset minor wear. Estate sales are prime hunting grounds because casual sellers often underestimate the worth of their record stacks.
12. Old Cameras and Photography Accessories

It’s easy to pass over old cameras thinking they’re obsolete. Dealers know that vintage photography gear, including lenses, tripods, and flash units, can be collectible. Specialty brands, historical models, or unusual accessories attract both collectors and hobbyists. Even parts can be sold to enthusiasts or restorers.
Collectors love provenance and rarity. Cameras that were used professionally or have unique markings carry extra value. Photography fans also hunt for early polaroid or medium-format cameras. Estate sales often leave these behind, making them a perfect target for dealers circling back for overlooked items.
