Not in the list? Most stamps are common
This checker covers famous rarities. The stamps in a typical album or shoebox are not those. As the UK auction house Warwick & Warwick puts it, the majority of stamps are worth very little because they were issued in huge quantities. The American Philatelic Society says the same about collections: most consist of relatively common material, and most of the value sits in a small part of them.
That is not a reason to throw anything away. It is a reason to identify a stamp before you assume anything about its value, and to find the few stamps that carry the value.
A famous design is not a famous stamp, either. Common printings, reprints and forgeries share many of the designs in this list.

What actually drives a stamp's value
Condition
Graders check for creases, thins, fading, toning, stains, tears and repairs.
Centering
How evenly the design sits within the perforations. Scott values assume Very Fine.
Gum
For unused stamps: never hinged, hinged, regummed or no gum, noted after the grade.
Perforations
Short or pulled perfs are faults, and the gauge can change the catalog number.
Cancellation
Most collectors prefer a light cancel; PSE takes points off for heavy or pen cancels.
Certificates
An expertizing service certifies the stamp as genuine and can grade it.
How to check a stamp's value, step by step
Identify the exact stamp, judge its condition honestly, then compare it with catalog values and real sales for the same stamp in the same condition.
- Identify it. Country, year, denomination and series come first. A photo-based identifier such as StampSnap gets you there quickly.
- Pin down the variety. Measure the perforation with our perforation gauge and check for a watermark with the watermark finder.
- Judge the condition. Look for faults on the front and back, then rate the centering with the centering grader.
- Look up the catalog value. Scott values assume Very Fine unless the listing says otherwise, so adjust for your stamp's grade.
- Compare real sales. Sold prices for the same stamp, grade and certification tell you more than any asking price.
Catalog value vs. selling price
A catalog value is a retail reference for a stamp in a stated grade. It is not what you will be paid.
Scott describes its catalog prices as retail prices, the amount you can expect to pay a dealer, for stamps in Very Fine condition unless a note says otherwise. Its introduction adds that the price you actually pay may be higher or lower because of many factors.
In practice, a discount from catalog is normal for a lot of material. The American Philatelic Society's marketplace column notes that many dealers sell worldwide stamps at a percentage of current catalog value, and online sellers often go lower. A dealer buying from you also needs room to resell.
For common stamps, keep the catalog minimum in mind. Scott notes that a set made up mostly of stamps at the 25-cent minimum value may be worth less than the total shown. Stanley Gibbons is blunter about its own 10p minimum: it signals that a stamp has no real commercial value, and a dealer will usually not pay anything for such stamps.
When to get an expert appraisal
Get a professional opinion when a stamp could be a valuable variety, when you need paperwork for insurance or an estate, or before a significant sale.
Keep the stamp exactly as it is in the meantime: no soaking, cleaning or pressing. Our stamp appraisal guide explains what an expert checks and how it differs from an online estimate.

Stamp value checker FAQ
How much is my stamp worth?
Start by identifying it exactly: country, year, denomination and catalog number. If it is one of the famous stamps in this checker, you can see an indicative range by condition. Most stamps are common and sell for little, so treat a match with a famous design as a reason to check closely, not as proof.
Where do the values in this checker come from?
They come from the condition ranges in StampSnap's stamp value guides, the same figures shown on each stamp's guide page. They are indicative ranges, not live market quotes and not an appraisal.
Why does my stamp look like a famous one but isn't worth much?
Many famous stamps share their design with common printings, reprints and forgeries. Perforation, watermark, color shade and paper can separate a rare variety from a common one, which is why expert certificates matter for valuable stamps.
Is catalog value what a dealer will pay?
No. Scott says its catalog values are retail prices for stamps in Very Fine grade, and that the actual price may be higher or lower. Many dealers sell worldwide stamps at a percentage of catalog value, and they buy for less than they sell.
