Example result
$900–1,400
A Swiss keyless movement of a type made in large numbers around 1900. The value rests mostly on the gold case; a named maker on the movement would raise it considerably.

The number decides what happens next
An $80 camera and a $2,400 clock should not be sold the same way. Your result points you down the right one of three roads.

How does Estimonia estimate value?
From your photos, it identifies the object — maker, period, materials, marks — and prices it against what comparable pieces actually sell for. You get a range rather than a single number, a confidence score, and the reasoning, so you can see why.
Is this a certified appraisal?
No. It is an informed estimate: good enough to tell a $20 item from a $2,000 one and decide what to do next. For insurance, tax or court you need an accredited appraiser — and the estimate tells you whether it is worth paying for one.
What can I value?
Antiques, heirlooms and collectibles: furniture, ceramics, silver, jewelry, watches, clocks, coins, stamps, art, toys, cameras, records and more. If it has a maker, a period or a market, it is worth a try.
What is free, and what costs money?
Valuations are free, with no account and no card, and so is the PDF report of a result. A few things are optional and paid: the $9.99 Sell-it Plan for items estimated at $300 or more, the Value Report for a whole collection or house, from $29, and Estimonia Pro, from $9.99 a month, for unlimited valuations. Nothing anyone pays changes your valuation.
Are my photos private?
Yes. Photos are never published, and nothing is shared with anyone unless you ask for it — for example, asking to be introduced to an auction house.
How accurate is it?
It depends on the object and the photos. Well-documented categories — watches, silver, coins, popular collectibles — come out close to real sale prices; one-off pieces carry a wider range and a lower confidence score, and the result says so. Clear photos of any marks or labels help most.
