How Much Are Stamps Worth?
The honest news first: the vast majority of stamp collections are worth far less than owners hope — common 20th-century stamps were printed in the billions. Value hides in specific places: pre-1920 stamps, printing errors, unused stamps with original gum, and complete sheets or covers with rare postmarks.

Real completed sales on eBay in the US — what buyers paid, not what sellers are asking. Each sale is checked to be the exact item; graded copies, lots, parts and Best Offer sales (where eBay hides the real price) are left out. Updated November 15, 2026 · 18 sales checked.
"Pay at most to flip" is FlipTip's rule of thumb for resellers — the typical sale ÷ 1.6, which leaves room for eBay's fee (about 13%), shipping and a solid profit; "—" = too cheap to flip one at a time. Tap a price to work out your own number.
"Typical sale" is the median. "Most sold between" is the middle of the market — the middle 70% of sales when there are six or more, otherwise the lowest to the highest. Your item's condition, completeness and exact version move it inside — or outside — that range, so scan yours for its own number — or see how to check eBay sold prices yourself.
Flipping stamps?
At the stall the question isn't what it's worth — it's the most you can pay and still make money after the fees and the shipping label. The "Pay at most to flip" column above gives a starting number for each model.

What decides the value of stamps
Age & scarcity
Pre-1900 classics (early national issues) carry real value. Most stamps after 1930 are common regardless of age or how exotic the country looks.
Mint vs. used
Unused ('mint') stamps with intact original gum are worth multiples of used copies. A hinge mark on the back cuts value significantly.
Errors
Inverted centers, missing colors, imperforate pairs — printing errors are where five- and six-figure stamps live.
Condition
Centering, intact perforations, no thins or creases. Grading is merciless: a torn corner turns a rarity into a spacefiller.
Typical price ranges
Broad secondhand-market ranges to orient you — the exact value of your item depends on the precise model, edition and condition. Scan it for the real number.
💡 How FlipTip prices it
Point your camera at the item. FlipTip identifies the exact model, edition and era, checks real listings on your country's marketplaces, and gives you a price range, a sell-speed score and a worth-it-or-skip verdict — before you buy or sell.
You also see the most to pay at the stall and your profit after fees. On paid plans and the free trial, in countries with a local eBay, the price comes with the item’s real completed sales — with dates you can open and check.
Stamps — FAQ
I inherited a stamp collection — how do I know if it's valuable?
Check for pre-1920 material, stamps with original gum, and anything that looks like a printing error. Albums full of colorful post-1950 stamps from many countries are usually decorative value only. Scan standout pages and let FlipTip flag which items are worth researching deeper.
Are old stamps on envelopes worth more?
Sometimes much more. 'Covers' with rare postmarks, first flights, or historical routes can outvalue the stamp alone. Never soak a stamp off an old envelope before checking.
Why is my '1-cent rare stamp' not rare?
Print volume. Famous designs were printed in billions and saved by everyone. Rarity comes from specific varieties — paper type, watermark, perforation count — not the picture.
