Free Antique Identification App: Identify and Value Antiques From a Photo

A pencil sketch of an antique ceramic vase, an ornate pocket watch and an old leather-bound book on a small wooden table, with a magnifying glass and a small price tag with a "$?" mark on it.

You inherited the box. Or you bought it at an estate sale. Or you walked past a stall at a flea market and felt the back of your neck tingle. Now you're holding a vase, a brooch, a clock, a dusty toy — and you have no idea whether it's worth $5 or $5,000.

This is what a free antique identification app is supposed to solve. There are a few that take a photo and try to identify the item — most are paywalled, slow, or load you up with ads. Costcam.app does it in a browser tab, for free, with no signup. Snap a photo, get an identification with brand and era cues if visible, plus a current market value range based on what comparable items are selling for online.

It is not a substitute for a Sotheby's specialist on a Ming vase. It is a substitute for "how much do you think Grandma's clock is worth, do you have any idea?", which is the question being asked 99% of the time.

What it does well

For most household antiques and collectibles, a photo is enough information for a useful first pass:

Mid-century modern furniture — readable silhouettes, often signed or stamped under the seat
Vintage cameras — Leica, Hasselblad, Polaroid, Pentax — model numbers are usually visible
Vinyl records — labels and sleeves photograph cleanly
Pottery and porcelain — maker's marks, glaze patterns, distinctive shapes
Watches and jewelry — brand stamps, hallmarks, design vocabulary
Toys — particularly Star Wars, LEGO, Hot Wheels, Barbie, anything boxed
Tools — Stanley planes, Disston saws, anything cast iron with a maker's mark
Books — first editions, dust jackets, signed copies (visible from the cover and copyright page)
Coins and currency — usually requires a clear front-and-back photo

What it can't do (and where to go next)

Authentication. A photo can suggest "this looks like a 1950s Eames lounge chair", but it can't tell you it's not a reproduction. For real money, you still want a specialist's hands on it.
Marks and signatures up close. If the value depends on a tiny stamp on the underside, take a separate close-up photo of the mark.
Damage you can't see. A vase that looks pristine in a photo might have a hairline crack in person, which can drop value 80%.
Provenance. Two identical paintings with different histories can have a 100x price spread. The app can't see the receipt from 1962.

For anything where the photo identifies a piece worth more than ~$500, the right next step is a specialist appraiser, not a confident-feeling app.

A practical workflow for an estate or a box of finds

If you've just inherited or bought a pile of items, here's the fastest way through:

Lay everything out somewhere with even, indirect light (a kitchen counter near a window works).
Photograph each item one at a time. Plain background. Get any maker's marks in a separate close-up.
Run each photo through costcam.app. Note the items it returns with high confidence and a meaningful value range.
Sort into three piles: likely valuable (worth a closer look), probably modest (sell or donate), and unknown / low confidence (research separately or take to a local antique dealer).
For the "likely valuable" pile, get a second opinion before listing or selling. Reputable auction houses and antique dealers will give you a free verbal estimate.

The categories where photo-based identification really earns its keep

A few categories have such well-defined visual languages that AI gets them right surprisingly often:

Mid-century lighting — Stilnovo, Arteluce, Sarfatti, even unsigned Italian lamps from the 60s
Studio pottery — distinctive throwing styles and glazes
Vintage watches — case shapes, dial layouts, brand-specific quirks
First-pressing vinyl — sleeve art and label details
Designer clothing — silhouettes, hardware, label fonts
Trading cards — the printing era is legible from the card design

Why a photo-first approach makes sense

Most online appraisal services either take days, charge per item, or want you to ship the thing in. A photo-based estimate gives you a faster signal — should I bother getting a real appraisal? — for free.
