Free Stamp Appraisal: Online, Video Call or Club Day

Published 2026-09-05 · Updated 2026-11-04

Online stamp appraisal can tell you roughly what you have, but it cannot replace handling the stamp or a formal certificate when real money is at stake. "Free appraisal" covers several different things, and they are not interchangeable.

Knowing which one you are being offered — and which one you actually need — prevents both wasted money and, more often, wasted opportunity.

What are the four kinds of free stamp appraisal?

A dealer's verbal assessment

Most stamp dealers will look at a collection and tell you roughly what it is, at no charge. This is genuinely valuable and it is also a buying conversation. The number you are given is a price the dealer would pay, which reflects wholesale economics and the years they may hold the stock. That is a fair trade, not a trick, but it is not an independent valuation and should not be treated as one. Ask two or three dealers, and ask each of them two distinct questions: what would you pay for this, and what do you think it would realise at auction. Both answers are honest and they will differ.

An auction house estimate

Auction houses assess material at no charge because they want the consignment. Their estimate is what they believe the item would fetch at sale, before commission. This is often the most useful free number available for genuinely good material, because their incentive is to be roughly right — an estimate set too high produces an unsold lot. They will decline material below their handling threshold. That refusal is itself information: it tells you the collection belongs in the bulk market.

A philatelic society

Local societies and national bodies frequently offer informal opinions at meetings or open days. There is no commercial interest, the people involved often have deep knowledge of a specific area, and it is the right level of help for working out what you have. It is advice, not a document.

Automated identification and valuation

An app or online tool that identifies a stamp from a photograph and gives an indicative range. Best used for triage — separating the handful of stamps that deserve real research from the hundreds that do not — and inherently limited by what a photograph can show. Gum condition, thins, creases, repairs and watermarks are not visible in a front-facing image, and those are exactly the things that move the price.

Every free route is good at the same thing: telling you which items are worth spending money on. None of them is a substitute for a formal document when a document is what the situation requires.

How do you get an opinion online, by video call, or at a club day?

If a dealer visit or an in-person society meeting is not practical, three remote options cover most of what people search for.

Online appraisal services working from photos

These services ask you to upload images and respond with a written opinion or a range. Send more than one photo: the front at straight angle, the back under good light, the stamp held against a light source so a thin or a repair would show, and a close, edge-on shot of the perforations. Even with all four, a photo-based opinion can only judge design, obvious damage, and rough identification. It cannot confirm gum originality, detect a fine regumming job, or measure a watermark reliably. Read the response carefully for whether it is phrased as an independent opinion or as "we would offer" — the second is a buying quote dressed as an appraisal, and the distinction matters as much online as it does with a dealer in person.

A video-call appraisal

A live call adds what a photo cannot: the assessor can ask you to turn the stamp, angle it under light, or hold it against a loupe or phone macro lens in real time. Prepare the way you would for any appraisal — good daylight rather than indoor bulbs, stamps grouped by country or issue so the call moves quickly, and your questions written down beforehand so you do not forget the one that matters once the call starts. The limits are real: a screen still flattens texture and colour, and no video call can substitute for an expert holding the item when a certificate is the eventual goal. Treat it as a step up from photographs, not as equivalent to an in-person review.

A club or society valuation day

Local and national philatelic societies and federations run valuation days or open evenings, usually on a published schedule rather than on demand, so it is worth asking well ahead of when you plan to sell. Bring stamps sorted by country or topic, any paperwork — old receipts, inventories, prior appraisal notes — and a short list of what you actually want answered. Etiquette matters here more than at a commercial appointment: these are often volunteers giving their time, so arrive with material pre-sorted rather than an unsorted box, and expect opinion rather than a formal written valuation.

If a mail-in service suits your situation better than any of these remote options, the mechanics of sending material to a recognised body for a written opinion are covered separately in stamp appraisal by mail.

When is a free opinion not enough?

Situation	What you need
Deciding whether to sell	Free opinions, two or three of them
Probate or estate valuation	A written appraisal from a qualified valuer
Insurance cover	A written appraisal, usually at replacement value
Division between beneficiaries	A written appraisal, for fairness and for the record
Selling a high-value single item	An expertising certificate
Disputed authenticity	An expertising certificate

Why do certificates pay for themselves?

An expertising certificate is not a valuation. It is a statement from a recognised body — the Philatelic Foundation and the American Philatelic Society's APEX service among them — that the item is genuine, correctly identified, and free of undisclosed repairs, regumming or alteration. For anything whose value runs well above pocket change, it usually pays for itself. Buyers discount uncertified material because they are pricing in the risk of a fake, and for famous rarities that risk is real: some forgeries are over a century old and were made with contemporary paper and ink. The fee is typically a base charge plus a percentage of assessed value, which is why it makes no sense on a low-value stamp and obvious sense on a genuinely scarce one. For background on whether paying for this step is worth it at all, see is it worth getting stamps appraised.

How do you get the most from a free assessment?

• Do the triage first. Arriving with a sorted set of candidates and a box of bulk gets you a better conversation than arriving with an unsorted carton — true whether the assessment is in person, by video call, or online.
• Bring the paperwork. Old receipts, auction cards, inventories and annotations tell an assessor in minutes what would otherwise take an hour.
• Do not clean or reorganise anything before the appointment.
• Ask what they are not valuing. Assessors focus on what they trade; material outside their area may be waved past rather than judged.
• Get a receipt itemising anything left with them, physically or by mail, and agree in writing what happens if it is not sold.

What warning signs should you watch for?

Unsolicited approaches following a bereavement notice, pressure to decide on the spot, and offers to take a collection away for valuation without a signed inventory are the three patterns that precede most bad outcomes. This applies online as much as in person: an unsolicited message offering a free online appraisal with an urgent deadline to accept an offer deserves the same suspicion as a stranger at the door. Legitimate dealers, auction houses and online services expect you to seek other opinions and will not object when you say so. A fuller list of these patterns is set out in stamp appraisal scams to avoid.

Common questions

Can a stamp be appraised online for free?

Yes, in the sense of a free opinion. Dealers, auction houses, societies and photo-identification tools will all give a view at no charge. None of them produces a written, independent valuation document — that is a separate, paid service, and it is only worth paying for once a free opinion has told you the stamp is a candidate.

Is a video call appraisal reliable?

It is more reliable than a single photograph, because the person assessing it can ask you to tilt the stamp, hold it to the light, or turn it over on request. It is still not as reliable as handling the stamp directly, and it cannot replace a certificate for a genuinely high-value item.

How do I find a stamp club valuation day near me?

Contact a local or national philatelic society or federation and ask about open days, valuation evenings or club meetings that include an appraisal slot. Many run these on a fixed schedule rather than on demand, so it is worth asking well before you plan to sell.

Should I trust an online appraisal tool's estimate?

Treat it as a starting range, not a final number. A tool working from a photograph cannot see gum condition, thins, or fine paper differences, all of which move the price. Use it to decide which stamps deserve closer attention, not to decide what to charge a buyer.
