What Is My Stuff Worth | Best Apps to Find Item Values in 2026

You just found a box of old jewelry in your mother's dresser. Or maybe you bought a storage unit at auction and have no idea what half the stuff inside is. Perhaps you are cleaning out an attic that hasn't been touched in 30 years, sorting through the accumulated possessions of a lifetime, and wondering: is any of this actually worth something?

This is the exact moment when a good item value app earns its keep. Instead of spending hours searching eBay, visiting antique dealers, or guessing, you photograph the item and get an answer. Some apps do this better than others. Some barely do it at all.

This guide compares the five most common apps people use to figure out what their stuff is worth, breaks down what actually makes a valuation app useful, and covers the categories where these tools matter most.

The 5 Best Apps for Finding Out What Your Stuff Is Worth

1. Underpriced AI

Best for: Getting instant identification and real market values for virtually any item

Underpriced AI is purpose-built for the "what is this and what is it worth?" question. You photograph any item -- vintage jewelry, antique furniture, old toys, electronics, kitchenware, designer bags, vinyl records, collectibles -- and the AI identifies it, then pulls real sold data from six or more platforms including eBay, Poshmark, Mercari, Facebook Marketplace, Etsy, and Depop.

What sets it apart from other tools is the combination of identification and pricing in a single step. You do not need to know what something is before you can find out what it is worth. The AI handles both. It tells you the item name, brand, era, and estimated value based on what identical or comparable items have actually sold for recently. Not guesses. Not asking prices. Completed sales.

The app also generates listing titles and descriptions if you decide to sell, and it breaks down pricing across multiple selling platforms so you can see where you would net the most after fees.

Pricing: Free to try with 3 scans. Subscription plans available for ongoing use.

Available on: iOS, Android, web, Chrome extension, and Firefox add-on.

Strengths:

• Photo-based identification means you do not need to know what you have
• Pricing comes from real completed sales, not estimates or algorithms
• Covers six or more selling platforms, not just one marketplace
• Works across a wide range of categories: clothing, jewelry, furniture, electronics, toys, coins, books, and more
• Generates ready-to-use listing titles and descriptions

Limitations:

• Subscription required beyond the initial free scans

2. Google Lens

Best for: Identifying items when you have no idea what they are

Google Lens is free and widely available, and it does a solid job of identifying items from photos. Point your camera at a vase, a painting, a piece of furniture, or an old gadget, and Lens will tell you what it is, often linking to similar items across the web.

The problem is what it does not do. Google Lens provides identification, but it does not give you market values. It might show you that your item is a McCoy pottery vase from the 1950s, but it will not tell you whether that particular piece sells for $15 or $150. You still have to take that identification and manually research pricing on eBay, Etsy, and other platforms yourself. For someone sorting through an entire house or storage unit, that manual research step for every single item is a massive time sink.

Pricing: Free.

Available on: iOS, Android, web, Chrome extension, and Firefox add-on.

Strengths:

• Completely free to use
• Strong visual identification across many categories
• Widely available on almost any device

Limitations:

• No market values or pricing data whatsoever
• Requires manual follow-up research for every item
• No sold data integration

3. Valuable (WhatIsItWorth)

Best for: Quick photo-based identification with some pricing context

Valuable (also known as WhatIsItWorth) is a newer entry in the item identification space. It allows you to photograph items and receive identification along with some pricing information. The app targets the same use case as Underpriced AI: you have something, you do not know what it is, and you want to know what it is worth.

The identification works reasonably well for common items, though the pricing data is more limited in scope compared to tools that pull from multiple selling platforms. The app is still building out its database and features, so accuracy and coverage can be inconsistent depending on the category.

Pricing: Free with limitations; premium features available.

Available on: iOS and Android.

Strengths:

• Photo-based identification and some pricing
• Clean, simple interface
• Growing feature set

Limitations:

• Limited pricing data compared to multi-platform tools
• Newer app with less established accuracy track record
• Coverage can be inconsistent across categories

4. WorthPoint

Best for: Deep research on antiques and collectibles when you already know what you have

WorthPoint is the most established research database for antiques and collectibles, with over 730 million sold prices in its archive. For serious collectors and antique dealers, it is an invaluable resource. The database covers auction results, online sales, and dealer prices going back decades.

The catch: WorthPoint is a research tool, not an identification tool. There is no photo-based identification. You need to already know what your item is -- or at least know enough to search for it. If you are staring at an unmarked piece of pottery or an unidentified piece of jewelry, WorthPoint cannot help you figure out what it is. And at $29.99 per month, it is a significant investment for someone who just wants to price a few things from a house cleanout.

Pricing: $29.99/month (Library plan), with higher tiers available.

Available on: Web only.

Strengths:

• Massive historical price database (730 million+ prices)
• Deep coverage of antiques and collectibles
• Includes auction results from major houses
• Maker's mark database for identifying stamps and signatures

Limitations:

• No photo-based identification
• Requires knowledge of what you have to search effectively
• $29.99/month subscription cost
• Web-only, no mobile app
• Overkill for casual use

5. eBay App (Barcode Scanner)

Best for: Pricing items that have barcodes (books, games, sealed retail products)

The eBay app includes a barcode scanner that lets you scan a UPC or ISBN and instantly see current and completed listings for that exact product. For books, sealed video games, retail electronics, and other items with intact barcodes, this is a fast and free way to check values.

The problem is obvious: most of the items people find in attics, garages, estate sales, and storage units do not have barcodes. Vintage jewelry does not have a barcode. Neither does antique furniture, old coins, vintage clothing, art prints, or first edition books from the 1940s. The barcode scanner is useful for a narrow slice of items and completely useless for everything else.

You can also manually search eBay for completed listings, but this requires knowing what to search for and takes considerably more time per item.

Pricing: Free.

Available on: iOS and Android.

Strengths:

• Free to use
• Instant results for barcoded items
• Shows both active and recently sold listings
• Direct path to listing if you want to sell on eBay

Limitations:

• Only works for items with barcodes
• Useless for vintage, antique, and collectible items
• No photo-based identification
• Only shows eBay data, not other platforms

What Makes a Good Item Value App

Not all valuation tools are created equal. When evaluating an app for figuring out what your stuff is worth, four things matter most.

Photo-based identification. The whole point is that you do not know what you have. A good app should be able to look at a photo and tell you what the item is. If you need to already know what something is before you can look it up, the app is a research tool, not a valuation tool. There is an important difference.

Real sold data. Asking prices are not values. Someone can list a vintage lamp for $500 on eBay, but if every sold listing shows $75, the lamp is worth $75. The best valuation apps pull from completed sales, not active listings or algorithmic estimates.

Multi-platform coverage. An item might sell for $40 on eBay and $80 on Poshmark, or vice versa. Apps that only check one marketplace give you an incomplete picture. The best tools aggregate data from eBay, Poshmark, Mercari, Facebook Marketplace, Etsy, and other platforms to show you the full market.

Speed. If you are sorting through a garage or an entire estate, you might need to evaluate dozens or hundreds of items. An app that takes 30 seconds per item is practical. One that requires 10 minutes of manual research per item is not.

Common Items People Want to Price

Certain categories come up again and again when people are cleaning out spaces and wondering about values. Here are the items most commonly scanned, along with what to know about each.

Vintage jewelry. Costume jewelry from brands like Trifari, Weiss, and Miriam Haskell can be surprisingly valuable. Signed pieces sell for 2-5x more than unsigned. Always check clasps and backs for maker's marks.

Rare coins. Date and mint mark determine everything. A common-date Morgan dollar might be worth $30 in silver value, while a key-date version in high grade could be worth thousands. Never clean coins -- it destroys their value.

Sports cards. Rookie cards drive the market. A PSA 10 graded rookie card can be worth 10-100x a raw copy. Condition is paramount: centering, corners, edges, and surface all matter.

Vinyl records. First pressings are the key to value. A first pressing of a classic album in near-mint condition can be worth hundreds or thousands, while a common reissue of the same album might sell for $10.

Antique furniture. Mid-century modern pieces from the 1950s-1970s are in highest demand right now. Maker's labels, stamps, and branded hardware can add 50-200% to a piece's value.

Designer handbags. Louis Vuitton, Chanel, and Hermes bags hold value remarkably well. Classic styles can retain 60-90% of retail value. Original dust bags, boxes, and receipts add a 10-20% premium.

Vintage clothing. Brand matters enormously. Certain vintage brands from the 1970s-1990s are worth far more than you might expect. Check all labels, including care tags that can help date the garment.

Vintage toys. Original packaging is the single biggest value factor. A boxed toy can be worth 3-10x more than the same toy loose. Star Wars, Transformers, LEGO, and Hot Wheels are consistently sought after.

First edition books. The dust jacket is often worth more than the book itself. Photograph both the title page and the copyright page for accurate edition identification.

Vintage watches. Originality matters more than cosmetic condition. A scratched original dial is typically worth more than a refinished one. Check the case back for serial and reference numbers.

Tips for Getting the Most Accurate Valuations

Whether you are using an AI-powered app or researching manually, the quality of your results depends on the quality of information you provide.

Take clear, well-lit photos. Natural light works best. Avoid flash, which washes out details and creates glare. A plain background helps the AI focus on the item rather than the clutter around it.

Photograph maker's marks and labels. Flip the item over. Check the bottom, the back, the inside of lids, the clasps of jewelry, and the tags of clothing. Maker's marks are often the single most important factor in determining value, and they are frequently hidden in spots people forget to check.

Capture all sides. Front, back, top, bottom, and any areas with unique features, damage, or identifying marks. A single photo often is not enough for accurate identification, especially for items where small details -- a date stamp, a signature, a specific hardware style -- determine the difference between a $10 item and a $500 item.

Note the condition honestly. Chips, cracks, stains, missing pieces, and wear all affect value. An accurate valuation requires honest condition reporting. A mint-condition estimate is meaningless if the item has significant damage.

Check for complete sets. If an item originally came with accessories, manuals, boxes, or matching pieces, the complete set is almost always worth significantly more than the individual parts. Before scanning, gather everything that belongs together.
