Valuation
Common Myths About Stamp Values
Many widely held beliefs about stamp values are simply not true. Age does not make a stamp valuable, rarity is worth little without demand, catalogue value is not the selling price, and a big collection is not necessarily a valuable one. Understanding the realities behind these myths is the surest way to value stamps sensibly and avoid disappointment.
At a glance
Why the myths persist
Stamps carry an air of mystery and history, and that invites hopeful assumptions: that anything old, rare or numerous must be worth money. The realities are less romantic but reassuringly simple, and knowing them protects you from both false hope and underselling.
Knowing the truth behind the common beliefs is the surest way to value stamps sensibly. Here are the ones we meet most often, each paired with the reality.
The myths, and the realities
Myth"It is very old, so it must be valuable."
RealityAge alone creates no value. Millions of Victorian stamps survive and are common. What decides value is scarcity, condition and demand, not the date on the stamp. See what affects a stamp's value.
Myth"It is rare, so it must be worth a lot."
RealityA scarce stamp that few people collect can be inexpensive, because value needs demand as well as rarity. And the word "rare" is used very loosely. See rarity and demand.
Myth"The catalogue says it is worth a certain amount, so that is what I will get."
RealityCatalogue value is a guide for a fine example bought from a dealer. The price a stamp actually realises is usually a fraction of it. See catalogue value vs market value.
Myth"It is a huge collection, so it must be worth a fortune."
RealityBulk is not value. Most of a large collection is common or cancelled to order, and a big catalogue total often just reflects minimum-priced common stamps. The value sits in a few items. See how to value a stamp collection.
Myth"Bright, colourful foreign stamps must be worth something."
RealityMuch colourful packet material is common or cancelled to order, and worth very little. See our guide to CTO.
Myth"First day covers are valuable and a good investment."
RealityMost modern first day covers were produced in large numbers and are worth little. A few early or special ones are exceptions.
Myth"Stamps always go up in value."
RealityStamps are not a guaranteed investment. Values rise and fall with demand and condition, and many stamps are worth less than was paid for them. The soundest reason to collect is enjoyment, not profit.
Myth"A dealer will pay me catalogue value."
RealityA dealer pays a wholesale price, below retail, because they carry the cost and risk of reselling, and an auction may get more for scarce material. That spread is normal in any trade. See catalogue value vs market value.
Myth"An error or misprint is always worth a fortune."
RealityOnly genuine, recognised errors that collectors want are valuable. Many apparent errors are minor varieties, common printing freaks, or even fakes, so anything unusual is worth having checked.
The simple reality
Behind all of these is one straightforward truth. A stamp is worth what it is worth because of its condition, its genuine scarcity and the demand for it, and because of what someone will actually pay. Nothing about age, bulk, colour or a catalogue figure overrides that.
Holding this in mind is the best protection there is, both against paying too much and against selling for too little. And if you would like an honest view of what you have, you are welcome to send clear photographs for a free valuation.
Frequently asked questions
Not by age alone. Many old stamps are common and inexpensive. Scarcity, condition and demand are what decide value.
No. Catalogue value is a guide for a fine example bought from a dealer. What stamps actually sell for is usually well below it.
Not necessarily. Bulk is not the same as value. Most large collections are mainly common or cancelled-to-order material, with value in a few items.
They are not a guaranteed one. Values rise and fall, and many stamps are worth less than was paid. It is wisest to collect for enjoyment.
Most modern first day covers are worth little, as they were produced in large numbers. A few early or special ones are worth more.
