An inherited shoebox of stamps: what to do first

Guides · 9 September 2026

A box of stamps arrives from a relative, and almost every first instinct damages it. Soaking stamps off their envelopes, peeling them out of an old album, sorting the "ugly" ones into a discard pile – each of these throws away exactly the information that decides what the collection is. The first session should remove nothing and destroy nothing.

Four things not to do

1. Do not soak anything off an envelope. On older material the envelope – the cover – is frequently worth more than the stamp, because the postmark, the route and the rate are the historical record. The reasoning is in the guide to postal history.
2. Do not peel stamps from album pages. Old hinges and dried glue tear paper; a thinned stamp is permanently reduced. Leave the page intact – see the guide to hinges and mounts.
3. Do not clean, press or repair. Erasers, tape, damp cloths and ironing all leave traces that any buyer reads instantly.
4. Do not discard by appearance. Faded, plain and dull stamps include most of the genuinely early material; bright and decorative ones are usually the mass issues.

Stabilise the box before sorting

Get it dry, cool and out of direct light, and away from any basement or attic swings in humidity. If items are stuck together by damp, do not pull them apart – set that group aside separately. Then split the contents into five physical groups without judging anything: loose stamps, album or stock pages, envelopes and postcards with stamps attached, first day covers and presentation packs, and paperwork – notes, receipts, correspondence. The last group is the one people throw away and later need, because it is the collection's provenance.

Sort in passes, never all at once

1. Pass one – country. United States in one pile, everything else in another. Do nothing else yet.
2. Pass two – era. Within United States, split before and after roughly 1940. Design and paper make this fast, and the older pile is where attention goes.
3. Pass three – unused or used. Gum on the back and no cancellation on the front means unused. What follows from that distinction is in the guide to mint versus used.
4. Pass four – format. Set aside anything that is not a single stamp: blocks, pairs, full sheets, booklets, stamps with tabs or margins.

A working method for a mixed pile, including how long each pass should take, is set out in the guide to sorting a mixed lot.

What actually matters in an American box

• Anything dated before 1900. Scarce survival, not scarce printing, is what makes early material interesting.
• Covers with clear postmarks, especially wartime, territorial or unusual routes.
• High face values and airmail, which were bought in far smaller numbers than ordinary rates.
• Multiples and full sheets, which are dispersed the moment a collection is split up and therefore survive rarely.
• Anything with a note attached. A previous owner who wrote "check this" was usually looking at something.

What rarely matters, in any quantity: used commemoratives from the second half of the twentieth century, mixed packets bought by weight, and anything torn, thinned or stuck down. Their volume is deceptive – a heavy box is not a valuable one.

Identify before valuing

A valuation of an unidentified box is guesswork. Work through issue, year and catalogue number first, following the five steps in the guide to identifying an old stamp, then write down what you have as you go, per the guide to cataloguing a collection. Only then is an outside opinion worth asking for, and the guide to preparing a collection for valuation covers what to bring.

Use the archive as the reference

Comparison is faster than reading. The open archive holds 2,136 United States stamps dated 1844 to 2024 – 444 before 1900, 695 from 1900 to 1945 and 930 from 1946 to 1991 – inside a wider set of 80,472 stamps from 271 countries and territories, which covers the foreign pile as well.
