A collection almost always outlives the person who built it.
It sits in a closet, or a safe deposit box, or three shoeboxes on a shelf in the room nobody uses, and it stays there quietly for years while the person who assembled it card by card knows exactly what is in it and why each one is there. And then, at some point, it belongs to somebody else — somebody who very likely did not choose it, was not there for any of it, and has no idea whether they are holding a few hundred dollars of cardboard or something that ought to be insured.
You might be reading this from one of three places. Perhaps you are the person who built the collection, and you have started to think, sensibly and a little uncomfortably, about what happens to it after you. Perhaps you are somewhere in the middle of that conversation with a parent, and finding it a difficult one to start. Or perhaps it has already happened, someone has died, and this has landed in your hands along with everything else that lands at once.
Wherever you are in that, one sentence does most of the work:
There is no hurry, and almost every expensive mistake made with a collection is made by someone moving faster than they needed to.
Cards do not spoil. No one else's deadline is yours. And the people most eager to help you decide quickly are — with real and honorable exceptions — the people who do best when you decide quickly. You are allowed to take three months to work this out. You are allowed to take a year.
What follows is what we would tell a friend. It is general information rather than advice about your particular circumstances, and it is not a valuation or an appraisal. Where you need a professional, we say so.
The most useful thing you can do for the people who come after you takes an afternoon, and it is not a legal document.
Write down what you have and why. Not a formal inventory — just enough that someone who knows nothing can tell the difference between the card that matters and the four hundred that don't. Which ones are graded and roughly what they are. Where the paperwork lives. Who you actually trust in the hobby, by name and phone number, because that turns out to be the piece nobody can reconstruct.
And say plainly which one you would keep. Every collection has a card that is worth more to the person who owns it than to anyone else alive, and unless you say so, the odds are very good that it gets sold in a lot for eleven dollars by somebody doing their best.
If it helps to know: the families who handle this well are almost never the ones with the most valuable collections. They are the ones where somebody wrote it down.
Most people should simply do this themselves, and everything above is written so you can. If you would rather hand it to someone, that is the thing we make — a written, photographed record of a collection, prepared one at a time.
If a collection has just become your responsibility, the work of the first week is essentially custodial. Move it somewhere dry, cool and locked, away from sunlight and out of any basement that has ever been damp — and bear in mind that attics are usually worse than basements, because heat is harder on cardboard than cold. If it is already somewhere sensible, leaving it exactly where it is remains a perfectly good answer.
Then, and this matters more than anything else in this section: do not try to improve anything. Do not clean the cards, with a cloth or an eraser or a solvent or your sleeve. Do not flatten a bent corner, trim a frayed edge, or brighten a surface. Surface dirt on an old card is expected and is already priced in; evidence of cleaning is not, and in the graded market it can move a card from valuable to essentially unsaleable. This is the single most costly well-meant act in the hobby, and it is almost always committed by someone trying to be helpful.
The same applies, even more absolutely, to the sealed plastic holders. If cards are in rigid cases with a printed label and a serial number, those are graded cards, and the holder is part of what makes them worth what they are worth. Opening one undoes that permanently.
Before you tidy, photograph the collection as you found it — in the boxes, in the binders, in whatever order it has been sitting in — because arrangement is sometimes information, and it is gone the moment you improve on it. Keep every scrap of paper you find with it, too: receipts, invoices, auction catalogs, letters, certificates, handwritten notes, even the box a card arrived in. Provenance, meaning the documented history of where a thing came from and who owned it, can carry real value, and it is usually thrown out in the first week by somebody being tidy.
One last thing, less obvious and worth saying plainly: be careful who you tell. A collection of real value, in a house that has recently had a death, at an address printed in an obituary, is a target.
You do not need to become an expert in any of this. You need just enough vocabulary that you are not at a disadvantage in a conversation.
A graded card is one that has been sent to a third-party company, authenticated, assigned a condition grade, and sealed in a tamper-evident holder — the "slab." A raw card has not been through any of that. The main grading companies are PSA, SGC, BGS/Beckett and CGC, and each slab carries a certificate number you can enter on that company's website to confirm the card is what the label claims.
The thing that surprises almost everyone is how completely condition drives value. The same card in near-perfect condition can be worth fifty or a hundred times what it is worth with softened corners, which means two cards that look identical to you across a kitchen table may not be remotely comparable in price. It also means a stack of the same player is emphatically not a stack of the same value.
It is also worth knowing, early and without embarrassment, that in nearly every collection a small handful of cards carry almost all of the value and the rest are worth roughly what it costs to mail them. That is not a judgment on the person who built it. Collections are assembled out of affection and curiosity, and neither of those is a pricing model. The cards that meant the most are frequently the ones worth the least, which is a perfectly good reason to have kept them.
Finally, on grading: sending raw cards in costs money per card and takes time, and for most cards it costs more than it adds. For a small number it can be transformative. That is a decision worth making with somebody who has no financial stake in the answer.
More confusion, and more genuine bad feeling, comes out of this than out of anything else in the process. When somebody tells you a card is "worth" a number, it is always worth knowing which of these four they mean.
1. Guide or "book" value. A published estimate, often out of date and frequently optimistic, and not a price anybody is under any obligation to pay. It is a reasonable place to start a conversation and a poor place to end one.
2. The asking price. What sellers are currently hoping to get. This is the number the internet shows you most readily, which makes it very easy to mistake for the value, but an asking price is a wish rather than a transaction. We should be straight with you here: the public index we publish on this site tracks asking prices, and we label it as such everywhere it appears.
3. The realized price. What somebody actually paid at auction, and the most honest number available to you. Two cautions come with it. The headline result usually includes the buyer's premium, the auction house's fee added on top, so the buyer paid more than the hammer price — and the seller, separately, paid a commission out of their own side. A card that "sold for $10,000" may well have put something under $8,000 in the seller's pocket.
4. What a dealer will offer you today. This is a wholesale price and it will sit meaningfully below the realized price, which does not automatically make it a ripoff. A dealer buying your card is putting up cash today, absorbing the risk that it doesn't sell, and taking on the work of selling it. You are being paid for speed and certainty, and the discount is what that costs. The difficulty is that a fair wholesale offer and a predatory one look almost identical to somebody who doesn't know the realized price — which is precisely why you find that out first.

Your address also brings you Weekend Reading, which goes out on Fridays: what the finest cards are actually selling for, and how serious collections get documented and looked after. That is the whole of what we send, and one click takes you back off it.
Start by finding out whether a record already exists, because serious collectors quite often left one and it saves an enormous amount of work. Look for an inventory, a spreadsheet, an insurance schedule, a will or trust that names the collection, or a folder of certificates. Beyond the practical value, it tells you what they believed they had.
Then sort the collection roughly into three groups — graded cards, cards that are obviously old, and everything else. You are not valuing anything at this stage, only getting the shape of it, and the first two groups are where your attention belongs.
With the graded cards, you can do a surprising amount yourself. Take the certificate numbers, look them up on the grading company's site, then search completed auction results for the same card in the same grade. An hour of that will usually tell you whether you are dealing with a few hundred dollars or something considerably more serious, and that single fact changes who you ought to be talking to.
The one genuinely time-sensitive item is insurance. Most homeowner's policies cap collectibles at a low sub-limit, often a few thousand dollars in total regardless of what is actually in the house, so if the collection turns out to be significant it is very likely underinsured as of right now. That is a question for the insurer or an agent, and it is worth asking early rather than after something happens.
The estate's attorney comes first, if there is one. Whether you may sell anything at all, and when, is a question about your legal authority as executor, and it sits ahead of every other question on this page. Do not sell estate property before you know you are permitted to.
A tax professional, early. Please do not take tax positions from a website, this one included — but do take that professional these questions:
The basis question in particular can matter a great deal and is very often missed entirely. Ask it early.
A qualified appraiser, if a filing requires one. Where you need a value for a tax return, an estate filing, a court, or an insurance schedule, what you need is a formal appraisal from a qualified appraiser — not a dealer's offer, not a printout from a website, and not us. The appraiser associations maintain searchable directories, and personal-property appraisers who handle collectibles do exist.
And more than one buyer, always. If and when you sell, get several independent offers on anything meaningful. An honest buyer expects exactly this and will not be remotely offended by it.
There are four common routes, and all of them trade the same two things against each other: how much you eventually get, and how quickly and easily you get it.
| Route | Typically gets you | Costs you |
|---|---|---|
| Major auction house | The strongest prices for genuinely significant cards | Seller's commission; months of waiting; they will decline ordinary material |
| Consignment to a dealer | More than an outright sale | A percentage, and time |
| Outright sale to a dealer | The least, and the fastest | The wholesale discount, in exchange for cash now |
| Selling it yourself online | Potentially strong for mid-value cards | Fees, your time, shipping, and real exposure to being scammed |
A sensible and very common answer is a combination of these: the few significant cards to auction or consignment, and the long tail sold in bulk to a dealer, simply because the tail costs more to handle one card at a time than it will ever return.
Whatever route you take, never let a collection leave your possession without a signed, itemized receipt setting out what was taken and on what terms. This is ordinary professional practice, and anyone reluctant to provide one has told you something useful.
You may have noticed that very little of the above is specific to sports cards.
Slow down. Find out what you have before you decide what to do with it. Learn the difference between what something is listed for and what it has actually sold for. Get more than one offer. Put it in writing. Keep the paperwork. Be wary of anyone who found you rather than the other way around, and warier still of anyone who needs an answer this week.
That is the whole of it, and it applies almost word for word to a coin collection, a stamp album, a garage full of tools, a wine cellar, a wedding ring, a piano, a car under a tarp, or a house full of furniture that somebody has offered to "take off your hands." Estates are settled badly for the same handful of reasons every time: the people responsible are exhausted, they are working with incomplete information, they are being approached by strangers who know more than they do, and there is a general and entirely false sense that all of it has to be resolved immediately.
None of it has to be resolved immediately. If you take one thing from this page and apply it to everything else in the estate rather than to the cards, we would consider that a better outcome than the one we wrote it for.
Somewhere in that collection there is very likely a card that mattered to the person who built it for reasons that have nothing whatever to do with money. The one their father gave them. The one they pulled at nine years old and carried around in a coat pocket until the corners went soft. It will not be the most valuable card in the collection and there is a fair chance it is worth nothing at all.
Find out which one it is, if you still can, while there is someone alive who remembers. Then keep that one, whatever you decide to do with the rest.
That isn't financial advice. It is just the only part of this page that nobody has ever regretted following.
The Heirloom Index is written by Gregory S. Ostrowski, a Certified Financial Planner™ professional who has collected since he was a kid, and for a long time now the kind of cards this site is about. This page exists because those two conversations — the hobby one and the financial one — are almost never had with the same person, and families in this position usually end up asking whichever one shows up first.
We do not buy cards and we do not broker them. We have no stake in what you decide to do with a collection, which is exactly what allows us to write this plainly.
We are also not appraisers, and we do not issue appraisals. What we do is write collections down — what is in it, what each meaningful card actually is, what the public auction record shows it has traded for, and what the family ought to know — so that whoever inherits it next is not starting from where you may be starting now. If you would like that done for your collection, tell us what you have — no payment, nothing committed. We write back with what we could make, what it would cost, and whether it is worth doing at all. If it isn't for you, this page is yours regardless, and you are welcome to print it, forward it, or hand it to a client.
This page is general information about a category of personal property. It is not legal, tax, insurance or investment advice, it is not an appraisal or a valuation, and it takes no account of anyone's particular circumstances. Please make decisions with a qualified professional who knows your situation.
