There are a few apps that can identify an item, but none that give a reliable resale price. Google Lens, eBay image search, and other AI chat assistants are all good at telling you what an item is. What it is worth is from sold listings on the marketplace you want to sell it on, adjusted for condition and fees/shipping.

## From photo match to a number you can trust

A photo app tells you what an item is, and a seller still has to determine what it sold for. They are two separate things. There are four kinds of photo tools you will run into. Visual search tools (Google Lens for example) match your picture against images across the web. Image search tools (the camera icon in the eBay app for example) match your picture against listings on that marketplace. AI chat assistants read a photo and tell you the brand/style/era/materials. Collectible apps are for a particular category (coins, records, antiques, cards, etc.).

The catch is what the match shows you. Visual search largely pulls up retail and active listings, so the price shown with the match is either what a store charged new or what a seller hopes to get. Ask yourself: why are they asking that price? It's because the listing hasn’t sold, and the longer a listing sits, the higher the seller hopes to get for it. The only price that shows what a buyer will pay is a completed transaction price.

Getting identification to match to your item works far better when you take the right pictures. Be sure to capture any and all labels (i.e. care labels, content labels, maker’s marks, stamps, serial numbers, etc.) as well as numbers or letters stamped on an inner seam of the item. Get close-ups of any hardware, pattern, embroidery, embellishments, or detailing. If the initial scan doesn’t work, take a picture of the label and/or tags.

1. Scan the item, tag, and/or label to get a match.
2. Search sold items on eBay from the last 90 days to get an approximate pricing guide.
3. Repeat for your selling platform of choice (i.e. Poshmark, Mercari, Depop, etc.).
4. Discard comps that don't match your size, color or condition. Also disregard the highest and lowest sales. Take the middle of the remaining sales as your starting point and adjust from there.
5. Five or six clean comps are usually sufficient. If you have fewer than three sales, treat it as a ballpark figure and price to sell.

Photo apps usually fail on the items resellers hope are valuable. Unbranded vintage, items made by hand, or items with a cut or missing label give the app little to match, so it returns a lookalike which could be worth much less or much more. Some counterfeit items trip the app up. If a bag is a known counterfeit, the app could compare it to the authentic model and show the authentic price.

## Where photo valuations go wrong and cost you money

Condition, and sometimes size, usually move the price the most. Sometimes a small feature like pilling or a broken zipper can significantly cut the price. Odor can definitely affect comps. A wool coat in November could be comped by a cashmere coat in March. Seasons shift demand and supply, so a cashmere coat in March may not sell for what it comped for in November.

Seasonality and demand changes sometimes mean larger or smaller sizes take longer to sell. Completeness sometimes affects how much an item is worth. For toys or bags a box, or for an electronic a charger, can greatly effect worth. For items that are always in demand, like coats or jackets, the lining or fabric may slightly change from season to season, which means it's always important to check the style number.

Work backward from your comp to a buy price when sourcing. Say your top sells for $40 on Poshmark. You keep $32 after fees and Poshmark takes the shipping label. Decide if your margin is good based on the comp and your time. Consider other factors like shipping costs on eBay or Mercari. Many sellers skip anything that will not clear at least three times its cost.

| Marketplace | What tends to shape the price |
| --- | --- |
| eBay | Deep sold history, strong for branded, collectible and technical items |
| Poshmark | Offers and bundles are common, so list above your target |
| Mercari | Broad buyer base, quick sales at moderate prices |
| Depop | Younger buyers, strong for vintage, streetwear and trend pieces |

Because buyers are different, you may need to list your comps at different places. If your comps are stronger at some places, list there. Or, list your comps at several places and let the first buyer decide.

## Frequently asked questions

### Do I need a paid app to value items?

For lower-priced items (clothing, shoes and home goods) there are a number of free resources to help you identify an item and see how much similar items are selling for (visual search apps, eBay sold filters, and sold filters for your selling marketplace). If you focus on one collectible category (like trading cards or coins for example), a paid app may be worth the cost as their databases may be more comprehensive.

### Can I trust an AI price estimate?

An AI assistant may be a good resource for helping you name the era or the material from a picture, but do not rely on their suggested price as they do not take into account comps on your selling marketplace. Always check recently sold items before you decide what to pay or what to list your item for.

### When is a professional appraisal worth it?

It may be worthwhile to invest in the app if you are selling higher end items (like signed collectibles, art, designer items that you can’t authenticate yourself). For your normal everyday items, use recently sold items as a comp.
