Collector Guide

How to document a collection before you need to

Almost nobody catalogs a collection while things are fine. It gets done after a fire, during an estate, or the week before a sale — which is exactly when the facts are hardest to recover and the person who knew them may not be around to ask.

This is what to record per piece and how to photograph it, in a form that holds up years later. None of it requires a product. A notes app and a phone camera will do, as long as you are consistent about the same handful of facts every time.

The facts worth recording, per piece

Ordered by how hard each is to reconstruct later. The ones at the top disappear first — they live in memory, not in the object.

What it actually is
The real-world identity of the piece, written the way a knowledgeable person would say it out loud — not a listing title, not an abbreviation only you understand.
The exact variant
Edition, print run, colorway, pressing, year, mint mark, trim — whatever distinguishes this specific version from the ten others that share its name. This is where most value lives and most catalogs are vague.
Where it came from
Who you got it from, when, and where. An estate sale in a named town in a named year is provenance. "Bought it a while back" is not.
What you paid
Kept privately. It is the fact you will most want and least be able to reconstruct — for insurance conversations, for capital gains at sale, and for knowing whether you are actually up.
Condition, stated plainly
In your own words, including the flaws. Grading opinions change and are contested; a specific written description of what the piece looks like does not.
Anything that came with it
Box, papers, receipt, certificate, original packaging, prior owner correspondence. Photograph these as carefully as the piece — for many categories the paperwork carries as much value as the object.

Four photographs per piece

More is fine. Fewer than these four tends to leave a gap someone can question.

01
The whole piece, evenly lit, plain background
This is the identification photo. It is not meant to flatter — it is meant to let someone confirm this is the same object later.
02
Any maker mark, signature, serial, or stamp, filling the frame
The single most useful photo you will take. It is what ties every other piece of documentation to this specific object rather than to its category.
03
Each flaw, individually and close
Documenting damage yourself protects you twice: it proves the flaw predates a shipment or a claim, and it makes every other thing you say more credible.
04
The piece with its papers and packaging together in one frame
A separate photo of a certificate proves a certificate exists. A photo of the certificate beside the object is what associates the two.

Keep the originals, and keep them somewhere else

Do not screenshot your own photos or re-export them through an editor — that creates a new file dated today and discards the capture data that made the original worth having. Keep the files as the camera wrote them.

And keep a copy somewhere the collection is not. Documentation stored in the same house as the pieces protects you against a dispute but not against the fire, the flood, or the theft — which are the events where it matters most.

What documentation can and cannot do

A record of your own is not an appraisal, an authentication, or an insurance policy. It does not establish what a piece is worth, does not certify that it is genuine, and does not obligate anyone to pay out. Those are separate things, done by separate parties, and anyone suggesting otherwise is selling something.

What it does is narrower and still worth the afternoon: it establishes what you had, what condition it was in, and what you knew about its history — at a specific time, in a form someone else can review. Appraisers, adjusters, executors, and buyers all start by asking for exactly that, and the collector who already has it is in a materially better position than the one reconstructing it from memory.

Or record it once and keep it

Everything above is free and worth doing on your own. COLLECTRS exists because doing it consistently across a whole collection — same fields, same shots, originals intact, findable years later — is the part people abandon around the twentieth piece. Records are free and unlimited; you only pay if you later want a listing kit exported for a sale.

Create a free record
COLLECTRS records what an owner documented at a point in time. It does not appraise, authenticate, grade, or insure, and it does not verify ownership. Nothing here is legal, tax, or insurance advice — confirm requirements with your own insurer or advisor.
