Valuing a stamp collection for an estate: probate, dividing it, dealer offers

Executors are often under pressure to clear a house quickly, and stamp collections are easy to sell badly in a hurry. A single cash offer at the door, accepted before anyone knows what is in the albums, is the most common way an estate loses money on a collection. It is also the easiest to avoid. Most collections are mainly ordinary material and worth less than the family hopes, but the few items that matter are worth finding before anything is sold or split.

Three jobs, three numbers

None of these is the catalogue total. Catalogues price each stamp in a stated grade at roughly full retail, so a sum of catalogue values written on the inside cover of an album is not a valuation. For why the gap is so wide, see why a stamp is worth less than its catalogue price.

Checklist for executors and families

1. Secure the collection. Move everything to one dry room, away from direct sun, radiators and outside walls. Do not leave albums in a garage or loft while the house is cleared.
2. Keep it as you found it. Do not soak stamps off envelopes, take them out of albums, split sets or throw away covers, letters, old price lists or the collector’s notes. Covers and the collector’s own records can be worth more than the loose stamps.
3. Look for paperwork. Purchase invoices, auction catalogues with lots marked, expertising certificates, insurance schedules and any inventory the collector kept. These speed up every later step.
4. Make a simple inventory. List each album, stock book and box, with a short description and photos of every page. Note any single items that the collector kept separately, in mounts, stock cards or a safe. They are often the ones that matter.
5. Ask the estate’s adviser what valuation is required for probate or tax, and by when. Do this before you sell, give away or divide anything.
6. Get the right valuation for that purpose (see below). If the collection is plainly modest, the adviser may say an informal estimate is enough. If it may be significant, a formal written appraisal protects the executor.
7. Agree with the heirs how the collection will be handled: sold, divided or one heir buying the others out. Put the method in writing.
8. If selling, get at least two written offers or an auction estimate before accepting anything.
9. Keep a record of what was sold, to whom and for how much. Executors are usually expected to account for the estate’s assets.

Valuation for probate or estate tax

Estates are generally valued at market value: what a willing buyer would pay a willing seller, as at the date of death. For a stamp collection that is usually much closer to what it would bring at a sale than to a catalogue or insurance figure. The guide to stamp collection value for estate tax explains the difference and why it matters.

Whether you need a formal appraisal depends on where the estate is administered, its total size and the value of the collection. A modest accumulation may only need a reasonable estimate. A collection that could be significant to the estate should be valued by someone independent, with experience of the material, who will put the basis and date of the valuation in writing. An appraiser who is also bidding to buy the collection has a conflict of interest. Use one or the other, not both in the same person.

A free or informal opinion still has a use here: it tells you whether a paid appraisal is worth commissioning. See whether it is worth getting stamps appraised.

Dividing a collection between heirs

Disagreements over collections usually come from the method, not the stamps. Agree the method first, in writing, before anyone looks for favourites. Common approaches:

• Sell and split the money. This is simplest and hardest to dispute, and it suits a collection no one wants to keep.
• Divide into lots of similar value. Group the material into lots by country or album, value each lot on the same basis, then assign them by agreement, by turns or by drawing lots. This only works if one valuation is applied to every lot.
• Take turns choosing. Heirs pick items or albums in rotation. This is fair on sentiment but can be uneven on value, so some families balance the difference in cash at the end.
• One heir buys out the others. This suits an heir who collects. It needs an agreed value that the others accept as fair, usually from an independent valuation.

Two cautions. First, a specialised collection, such as one country studied in depth or a run of covers from one place, can be worth more as a whole than in parts. Splitting it can lower its total value for everyone, so ask the valuer whether it should be kept together. Second, keep items of purely sentimental value out of the valuation pot by agreement. That avoids arguments over a few pages that matter to one person and are worth little to a buyer.

If the estate is divided under a will or an intestacy rule, the executor’s duties come first. Check with the estate’s adviser before you agree any division that differs from what the will says.

Dealer offers: how to read them

A dealer’s offer is a wholesale price. The dealer takes the risk, the time to sort the material and the cost of reselling it, so on ordinary stamps an offer will be a small fraction of catalogue. That is normal, not a sign of bad faith. What protects the estate is comparison and clarity:

• Get offers in writing, stating exactly what they cover: the whole collection, or named albums or items.
• Get more than one. A second offer is the quickest way to see where the real range is. See how to negotiate with a stamp dealer.
• Watch for cherry-picking. An offer for “just these few” can leave the estate with the bulk that no one else wants. Ask for a price on the whole as well.
• Separate the valuer from the buyer. A free valuation from the person making the offer is a negotiating position, not a valuation.
• Do not let material leave without a receipt that lists what was taken, by whom and for what purpose.
• Ignore time pressure. An offer that is only good “today” is a reason to decline it. The guide to stamp appraisal scams to avoid covers the usual patterns.

For scarce or specialist material, an auction may bring more than a dealer, after the seller’s commission and charges are taken off. Compare like with like: a dealer’s cash now against an auction’s net proceeds later. See stamp auction consignment fees and auction versus selling online. For the wider choice of venue, see where to sell stamps.

Common questions

How is a stamp collection valued for probate?

Generally at market value as at the date of death: what a willing buyer would pay, not the catalogue total or an insurance figure. Whether you need a formal written appraisal depends on where the estate is administered and its size, so ask the estate’s solicitor, lawyer or accountant before you commission one.

How do you divide a stamp collection fairly between heirs?

Agree the method in writing before anyone chooses. Either sell and split the money, divide the material into lots valued on one agreed basis, take turns choosing and balance any difference in cash, or let one heir buy the others out at an independent value. Ask a valuer whether a specialised collection is worth more kept together.

Should I accept a dealer’s offer for an inherited stamp collection?

Not the first one, and not on the spot. Get at least two written offers that state exactly what they cover, and ask for a price on the whole collection as well as on selected items. A dealer’s offer is a wholesale price, so it will be well below catalogue on ordinary material.

Can an app value a stamp collection for an estate?

No. An app estimate helps you find the items worth a closer look and keep a record of what was there, but it is not a probate valuation or an appraisal. Where the estate needs a formal figure, use an independent, qualified appraiser.
