You found something in the attic. Or at a garage sale. Or maybe you’re cleaning out a relative’s house and came across a box of stuff that looks like it might be valuable.
Now you’re staring at it thinking: what is this worth?
This question is probably the most searched thing by anyone who’s ever found something old, rare, or just plain confusing. And for good reason. Nobody wants to sell something for $20 when it’s actually worth $200. And nobody wants to waste hours researching something that’s genuinely worthless.
Here’s how to figure out what anything is worth, fast.
The Simple Truth About Value
Before we get into methods, let’s be clear about what “worth” actually means.
An item is worth whatever someone will pay for it. Not what you think it should be worth. Not what some price guide says. Not what your grandma told you she paid for it in 1965.
The market sets the price. Your job is to find out what the market is saying right now.
Method 1: Check eBay Sold Listings
This is the fastest and most reliable way to figure out what something is worth. And it’s free.
Here’s the process:
- Go to eBay.com
- Search for your item (be specific with brand, model, condition)
- Click “Sold Items” in the filter sidebar
- Look at what items actually sold for in the last 30 to 90 days
The prices in green are what people actually paid. Not what sellers are hoping to get. Real transaction data.
If you search “vintage Pyrex mixing bowl green” and see sales at $35, $42, $45, and $50, you now know your bowl is probably worth around $40 to $50.
This takes about 60 seconds and gives you real market data.
Method 2: Use a Price Checker App
Sometimes you don’t have time to manually search eBay. Maybe you’re standing in a thrift store trying to decide if something is worth buying. Or you’re at an estate sale and there’s a line behind you.
That’s where a price checker app comes in handy.
A good price checker app lets you take a photo or screenshot and instantly get pricing information. It pulls in data from multiple marketplaces and tells you what the item is worth.
This is especially useful for:
- Sourcing at thrift stores
- Making quick decisions at garage sales
- Researching items you don’t recognize
- Getting a deal score before buying on Facebook Marketplace
Method 3: Google the Specific Item
If you have a brand name, model number, or any identifying information, just Google it.
Search for something like “vintage Schwinn bicycle value” or “Fiesta dinnerware orange plate worth” and you’ll often find collector forums, price guides, and discussions about that exact item.
Be careful though. Random websites often show outdated or inflated values. Always cross reference with actual sold listings to confirm.
Method 4: Check Multiple Marketplaces
Different platforms have different buyer pools, which means different prices.
An item might sell for $80 on eBay but only $50 on Facebook Marketplace. Or something might do better on Poshmark than Mercari because the right buyers are there.
When researching value, check:
- eBay (best for most items, largest buyer pool)
- Facebook Marketplace (good for local items, furniture)
- Poshmark (strong for clothing and fashion)
- Mercari (solid general marketplace)
- Etsy (vintage items and handmade goods)
The highest price you find is probably the ceiling. The lowest is the floor. Reality is somewhere in between.
How to Research Items You Can’t Identify
Sometimes you find something and have no idea what it even is. No brand name. No model number. Just a thing.
Here’s what to do:
Start by describing what you see. Material, color, approximate size, any markings or stamps.
Search Google with a description: “vintage green glass bowl with gold trim” or “brass figurine woman holding basket.”
If that doesn’t work, try Google Lens. Take a photo and let image recognition help identify it.
Check the bottom of items for maker’s marks, stamps, or signatures. These are often the key to identification and value.
Join collector groups on Facebook or Reddit and post a photo. People who specialize in specific categories can often identify items instantly.
What Makes Something Actually Valuable
Not everything old is valuable. Not everything rare is valuable either. Here’s what actually drives value:
Demand is the biggest factor. Something has to have buyers who want it. A rare item nobody wants is still worthless.
Condition matters enormously. A mint condition item might be worth 10x what the same item in poor condition sells for.
Completeness affects value. Original packaging, accessories, and documentation all add value.
Authenticity is critical for branded items. Fake designer goods are worth nothing. Real ones can be worth thousands.
Current trends play a role. What’s hot today might not be hot next year. Vintage fashion, retro gaming, and certain collectibles go through cycles.
Common Items That Are Worth More Than You Think
Some things people throw away or donate are actually valuable:
Vintage clothing from certain eras and brands. 90s streetwear, vintage band tees, designer pieces.
Old electronics that still work. Retro gaming consoles, vintage audio equipment, early Apple products.
Vintage kitchenware. Pyrex, Le Creuset, cast iron with certain maker’s marks.
Old tools. Quality vintage hand tools, especially from certain manufacturers.
Books. First editions, signed copies, certain textbooks.
Toys. Vintage action figures, board games with all pieces, anything sealed in original packaging.
Common Items That Are Worth Less Than You Think
Some things seem valuable but really aren’t:
Beanie Babies. Unless you have the extremely rare tags and variants, most are worth a few dollars.
Encyclopedia sets. Almost impossible to sell. Nobody wants them.
Most china and dishware. Unless it’s a highly collectible pattern, it’s hard to sell.
VHS tapes. A few rare titles are valuable, but most are genuinely worthless.
Mass produced “collectibles.” Franklin Mint, commemorative plates, most stuff sold as collectible at purchase.
The “Is This Worth Flipping” Calculation
If you’re trying to decide whether to buy something to resell, you need to think beyond just value.
Here’s the quick math:
Take the expected sale price based on sold listings.
Subtract platform fees (usually 10 to 15 percent).
Subtract shipping costs if applicable.
Subtract what you’d pay to buy the item.
What’s left is your profit.
If the profit is under $10, it’s probably not worth the time to clean, photograph, list, pack, and ship the item.
A good rule of thumb: only buy things you can sell for at least 3x what you pay. That leaves room for fees, shipping, and profit.
When to Get a Professional Appraisal
Most items don’t need professional appraisals. The methods above will tell you what you need to know.
But sometimes professional help makes sense:
Fine jewelry and watches. Authentication and detailed assessment matters.
Art and antiques. Provenance and condition affect value significantly.
Rare collectibles. Sports memorabilia, historical items, high end collectibles.
Insurance purposes. If you need official documentation of value.
If something might be worth thousands, spend the money to get it properly appraised before selling.
The Bottom Line
Figuring out what something is worth doesn’t have to be complicated.
For most items, check eBay sold listings. It takes a minute and gives you real market data.
For faster research, use a price checker app that can analyze items from a photo.
And remember: value is what someone will pay, not what you hope to get. The market tells you the truth. Listen to it.
Now go find out what that thing in your closet is actually worth.
