Value of Stamps?

[snip]

Rey--I don't specialize in U.S. revenues, so I'll leave that
question to others. But almost all U.S. stamps issued since 1934
(or thereabouts) were printed in such large quantities that supply
far exceeds demand. With rare exceptions--perhaps a few dozen--
they are worth no more than face value, even as plate blocks,
full sheets, etc.

Thank you very much for your information, Stan.

I'm still hoping other posters will reply.

Hello

You are hoping for other answers. I expect that means more positive
answers.

Bonjour, Richard,

Well, I trust Stan's and your information 100% that all my 29-cent
stamps are worth only 29 cents. What I was hoping for was more info
about this rare old stamp (ca. 1850?):

"U.S.INTER.REV. - PROPRIETARY" - four cents. It has two small white
spots (1 mm). This stamp can be seen here (124K .jpg):

On the Web, I have seen such "U.S.INTER.REV. - PROPRIETARY" stamps sold
for $300 to $3,000 and one auctioned off for about $30,000! Thus I'm
curious whether mine is worth *something*.

To the contrary, I would qualify Stan's answer by saying that the
stamps are worth face value only to the ultimate user who will put
them on his outgoing mail.

Of course. That's what I'm doing now, adding to the 29-cent a 20-cent
stamp for the 1-ounce letter costing currently 49 cents postage.

If you have any quantity of stamps it will take a long time
before you use them all.

Right, it'll take several years.

If you try and sell them either to a wholesaler or to a large user,
you will find that it is difficult to get more than 50 - 60% of face
value depending on the face value of each stamp.

No, I wouldn't be that stupid and throw away some $35 by selling them to
a wholesaler (Their motto: "Buy low, sell high.").

You won't get 50% for 4¢ stamps, but you might get a bit over
50% for 40¢ stamps.

I have only one old 4-cent stamp (see above). I can't even use it for
postage, as it's a "U.S.INTER.REV. - PROPRIETARY" stamp.

Thank you for your information, or as they say in French,

« Merci mille fois pour votre information ! »
