Here’s an easy way to find a stamp’s value without using a catalog by searching online. Just follow these simple steps and search the stamps
at an auction online.
When Issued?
The first step is to narrow down the identity of your stamp so that you can search for it more efficiently.
Read the inscriptions on your stamp. They often say when they were issued and help to identify the stamp.
All stamps of the 19th century were engraved; printed from etched printing plates. The design is a series of solid lines of color, similar to the central portraits on American paper money.
If you think your stamp is from the 19th century, go to an American listing on :: Online Stamp Catalogs.
Non-engraved stamps are from the 20th century and these have the same appearance as pictures in glossy magazines. They are often in full-color.
Commemorative or Definitive
Nearly all stamps that commemorate a specific event were issued in the 20th century, and commemoratives are nearly double the size of the ordinary postage
stamps. The first US commemoratives were issued in 1892 to celebrate Columbus’ arrival in the Americas.
Definitives are generally printed over and over again in large quantities throughout the years as needed, while commemoratives go through one printing of a certain quantity.
Search Online Stamp Auctions
Once you have narrowed down the search for your stamp, go online to a large auction site like eBay to search for comparable stamps offered at auction. Note that this process can work for first day covers, postal cards and other philatelic items.
There are many online auction houses, but the largest is eBay so that’s the place to start. However, you can use a similar strategy on just about every auction service.
Search Without a Catalog #
Let’s suppose that you have an American stamp you want to know the value of, here’s how to get started. Go to :: eBay: Recently Completed Stamp Auctions.
From here choose the closest possible category to your stamp. Is it unused or used, 19th or 20th century?
“Unused” (or mint) refers to stamps that have not been used in the mail or canceled. Most times they still have their original gum (og) on the back. “Used” refers to any canceled stamp that has been used on a letter or card.
Say, you have an unused stamp that you think is from the 19th century, click “United States : 19th Century:Unused.” You’ll get 1500 or more listings, so you must use the “Search” box to find what you’re looking for.
Many sellers use catalog numbers plus a few words to describe their offerings in the title. If, for example, your stamp is a three-cent stamp, put “3c” in the search box, no quotes and, if you know who is pictured on the stamp, put the name in too. Hint: many 19th century stamps picture George Washington or Ben Franklin.
Select “Search only in United States : 19th Century:Unused” and “Search titles and descriptions.” Then click “Search.”
Then compare your stamp to those in the search results that are listed with pictures, and hopefully you’ll find a copy of your stamp. Most of the stamps will also be listed with a catalog number, for example, “U.S. Stamps - # 26 3c Washington Mint LH.”
Search Again
Take this catalog number and put it in the search box and re-run your search, but be sure to run the search from the same stamp category page you ran your first search from and not the search results page. Just click your browser’s back button.
When I searched for “washington 3c” I got 2 results. When I searched for “26,” I got ten.
Check Closed Stamp Auctions
These stamps are currently at auction. To see what stamps similar to yours have already sold for on the auction service, stay on the current results page, un-select “Search titles and descriptions (to find more items!)” and click “Search Completed Items” right next to it.
You’ll get closed auction results. Unfortunately, many of the stamps’ scans may not still be available a few weeks after an auction closes, but you’ll have final dollar amounts to check.
Non-USA Stamps
This online search method works for all stamps, but if you can’t identify your stamp check out this page :: Stamp Identifier.
Condition and Grading
A stamp’s condition determines the value. The better the condition the more valuable the stamp, and any injury to the stamp after it left the printing plant is considered a fault. Stains, tears, creases, scrapes, pinholes and toning are all faults that lessen the stamp’s value, some considerably.
Grading is a way to describe how neatly centered the stamp design is on the paper. A stamp is usually valued with a grade of just “very fine” VF, which means the stamp is just off-center, either top-to-bottom or side-to-side.
A stamp with four equal-sized margins between the design and the edges is considered to be “extremely fine” EF, a grade higher than VF. To learn about grading and condition read :: Stamp Grading and Condition .
