If you just inherited a stamp collection, the single most important thing you can do right now is nothing drastic. Do not clean the stamps, do not soak anything off paper, and do not sell in a hurry. Handle everything with tongs instead of your fingers, get the collection into one stable stockbook so nothing gets lost or damaged, decide whether you actually want to keep it or sell it, and only then think about appraisal. Collections that arrive at a dealer organized and properly presented get looked at faster and priced more fairly than a shoebox of loose stamps. Here is the step-by-step version.

Step 1: Handle it safely from day one
Fingers leave oil behind, and oil is exactly what damages paper and gum over time. Before you touch a single stamp, pick up a pair of stamp tongs. They are inexpensive, and they are the difference between a collection that holds its value and one that quietly loses it while you sort through a box on the kitchen table.
Storage matters just as much as handling. If the collection came to you in stockbooks, resist the urge to stack them flat on top of each other on a shelf or in a box. The weight of books stacked above bends and creases the stamps in the ones underneath, especially anything mounted near the edge of a page. Store stockbooks upright, spine out, the same way you would shelve regular books. It costs nothing and it is the single easiest way to prevent damage you would never be able to undo.

Step 2: Get everything into one stable system
Inherited collections rarely arrive tidy. You might have a mix of loose stamps, a partly filled album, glassine strips, and a cigar box of miscellaneous covers. The goal here is not to make final decisions about value, it is to stop the bleeding: get everything into a stockbook so nothing gets lost, mixed up, or handled more than it needs to be.
A stockbook with glassine strips lets you slide stamps in and out without hinges, mounts, or adhesive, which matters because you do not yet know what is common and what is scarce. Sort loosely by country or era as you go if you want, but the real job of this step is consolidation, not curation. One organized stockbook beats three shoeboxes every time, both for your own sanity and for what a dealer will think when they open it.

Step 3: Decide if you want to keep it or sell it
Before you go any further, ask yourself the question that actually matters most: is this about the money, or does the collection mean something to you personally? There is no wrong answer, but it changes everything downstream.
A stamp collection is rarely just stamps. Someone spent years, sometimes decades, deciding what to chase next, what to trade for, what mattered enough to save. Sorting through it often tells you more about that person than you expected: the countries they dreamed of, the events they cared about, the years they collected hardest. Keeping and continuing the collection, building on the same countries or topics they were working on, is one real way to carry that forward instead of just storing it.
If the collection includes a lot of mint, never-used stamps, there's another way to keep it alive: use them. Postcrossing, a global postcard exchange with more than 800,000 members in over 200 countries, runs on real mint postage. Sending those inherited stamps out into the world on real mail puts them back into circulation and starts something new, rather than leaving them to sit in an album.
If you want to keep and build on what you inherited, the next steps are about doing that properly. If you want to sell, the next two steps are about getting a fair price without a rushed, disorganized handoff.
Step 4: Pull out the standout pieces and present them right
Once the bulk of the collection is safely in a stockbook, go back through and flag anything that looks unusual: high catalog values in a Scott or Michel catalog, plate blocks, first day covers, varieties, or anything that looks old, scarce, or simply different from the rest. These are the pieces where presentation actually changes the outcome.
This is where approval cards come in, and they are worth understanding correctly. Approval cards are not just for display, they are the industry-standard format dealers, grading services, and auction houses expect when you submit individual stamps for certification, grading, or consignment. A stockbook is right for the bulk of a collection. A rigid, crystal-clear approval card is right for the handful of pieces that might actually be worth grading or auctioning individually, because it protects the stamp during handling and shipping and it signals that you know what you have. Mount your best candidates on approval cards before you approach a dealer, grading service, or auction house about them specifically.

Step 5: Get it appraised the right way
For the bulk collection, a reputable local stamp dealer or a referral through the American Philatelic Society's inherited collection resources is a solid starting point. For the standout pieces you set aside in Step 4, and especially for anything you suspect could be genuinely valuable, do not stop at one opinion. Get it looked at by more than one dealer or, for higher-value pieces, a recognized auction house or grading service. Appraisals can vary more than people expect, and a single quick offer from one buyer is not the same thing as knowing what a piece is actually worth. A second or third opinion costs you a little time and protects you from leaving real money on the table.
If it turns out most of the collection is common material, and keeping it doesn't appeal to you, donating it is a genuinely good outcome, not a consolation prize. Local stamp clubs regularly take collections for member trading, youth outreach, or club auctions, and the American Philatelic Society can help you find one near you. It keeps the hobby alive for the next person instead of the collection ending up in a closet or the trash.
Common mistakes to avoid
| Mistake | Do this instead |
|---|---|
| Cleaning or soaking stamps to make them "look better" | Leave them exactly as found; cleaning almost always destroys value |
| Handling stamps with bare fingers | Use stamp tongs every time, even for the "junk" ones |
| Stacking stockbooks flat on top of each other | Store them upright, spine out, like books on a shelf |
| Taking the first offer from a single dealer | Get at least one more opinion, especially on standout pieces |
| Selling before deciding whether you actually want to keep it | Sort and sit with the collection for a bit before deciding |
Frequently asked questions
Is my inherited stamp collection worth anything?
Maybe, and often more than you'd guess. Most inherited collections are a mix of common stamps with little individual value and a small number of standout pieces that carry most of the real value. The only way to know is to sort it, get it into a stockbook, and have it looked at.
Do dealers really pay more for a well-organized collection?
They pay more attention, at minimum, and often more money too. A dealer who has to spend hours untangling a shoebox of loose stamps will price in that time, or simply lowball it to move on faster. A collection that's already sorted into a stockbook, with standout pieces set aside on approval cards, looks like it came from someone who knows what they have.
Should I clean old stamps before selling them?
No. Cleaning, soaking, or trying to remove stamps from covers you're unsure about can destroy the exact condition that determines value. Leave everything as you found it until a dealer or appraiser has seen it.
What's the difference between a stockbook and a stamp album?
A stockbook has glassine or plastic strips you slide stamps into, so nothing needs to be hinged or mounted. That makes it the right tool for sorting and organizing quickly. A stamp album has printed pages for specific countries or years, meant for a finished, curated collection. Start with a stockbook, move standout pages into an album later if you decide to keep and build the collection.
*IMPORTANT NOTE: Ensure the stockbook you choose is pH-neutral, acid-free or archival-grade. Read more on archival materials here.
Where can I get an inherited stamp collection appraised?
Start with a reputable local stamp dealer, or use the American Philatelic Society's referral resources to find one. For anything you suspect is genuinely valuable, get more than one opinion before you sell.
Quick glossary: terms used in this guide
New to stamp collecting? Here's what the terms above actually mean.
Scott catalog / Michel catalog
The standard reference catalogs collectors and dealers use to identify stamps and look up market value. Scott is the standard in the US, Michel is the standard across Germany and much of Europe. A stamp's "Scott number" or "Michel number" is essentially its official ID.
Mint vs. used
Mint means a stamp was never postmarked or mailed, and still has its original gum. Used means it was actually mailed and typically carries a postmark. Mint usually carries more value, but not always, some used stamps with rare cancellations outvalue their mint counterparts.
Stockbook
A book with glassine or plastic strips you slide stamps into for storage and sorting, no hinges or adhesive required. The right tool for organizing a large or newly inherited collection quickly.
Postcrossing
A global postcard exchange project, active since 2005 with more than 800,000 members in over 200 countries, where participants mail real postcards to strangers worldwide using real postage. A popular way to put inherited mint stamps back into use.
Stamp tongs: spade, pointed, and round tip
Tweezer-like tools for handling stamps without bare fingers. Spade, or round tip tongs are broad and give the most protection, a safe default for most collectors. Pointed tip tongs are precise but can tear delicate stamps if you're not careful, more of a professional's tool. Round or spade tip tongs sit in between, a solid balance for beginners.
Covers
A cover is an entire mailed envelope, complete with its stamp and postmark, kept intact rather than having the stamp removed. Covers can be worth more than the stamp alone, especially first day covers or ones with unusual routing or cancellations.
Hinges and mounts
Hinges are small adhesive strips that attach a stamp to an album page, cheap but they can leave a mark on mint stamps. Mounts are clear plastic sleeves that hold a stamp without adhesive touching it directly, the better choice for protecting a mint stamp's value.
Approval cards
Rigid, crystal-clear cards used to present individual stamps for grading, certification, or auction consignment. This is the actual industry-standard format dealers, grading services, and auction houses expect, and SAFE's approval cards are widely regarded as the professional benchmark in that category.
