How NOT to identify a Stamp
  • Start by looking up, in a catalog or on ebay, the most expensive variety your stamp might be.

  • Ignore perforations, watermarks, printing and paper types, and instead only measure the stamp design.

  • When measuring, make sure you know the 'rare' stamp dimensions so you can influence yourself.

  • Also make sure that you are using a poor quality ruler, pay no attention to the way you align the marks on the ruler.

  • Ignore the fact that any dimension that you have read are only estimates and absolutely have no tolerances are mentioned.

  • Do not let any logic influence you; always assume that you do not have a stamp in which billions were printed. Instead assume that you have a previous unknown and extremely rare stamp.




How To Identify a Stamp
  • Start by looking up the most likely, common variety your stamp might be and see if yoru stamp matches it.

  • Gauge the perforations, check for watermarks (if applicable), and learn printing and paper types.

  • Do not try to measure a stamp design, instead make a template from other known stamps and compare.

  • Always start with the assumption that you have the most common variety. This greatly reduces the chance that you will suffered from confirmation bias.

This no-nonsense, logical approach to stamp identification will not make our new members happy.

I much prefer the easier 3-step approach:

1) Find stamp
2) Discover rarity worth hundreds of thousands of $$ on the internet!
3) Assume my stamp is said rarity!!

With this in mind I recently formulated a decision tree for identifying the types of the 1851-57 One-Cent Franklin that would lead users to the common types first (as opposed to looking through the Scott catalog in numerical order, for example). It's in PowerPoint, however, a file type which I do not believe can be uploaded here.

Mdroth, that's Step 1.
Step 2 will always be:

Dudley, you can save each slide as an image and then upload them to a new post.

Dudley,
Sounds good, if you would like to send it to me I can take a look at what might done to code this logic into an online tool. It would make a nice addition to the new Stamp Smarter 1¢ 1851-57 Plating Initiative.

This new community database (Admin is fellow SCF member Richard Nance) is just getting underway and allows folks to search on Type, Relief and Scott number.

Or as a certain Internet meme would have it:

1) Find stamp
2) ????
3) PROFIT!!!!

Unfortunately there is a class of dealers whose sorting algorithm is based solely on the highest possible price.

An interesting example is Denmark Scott 122/122a. There is a 9 times difference in catalog value for these 2 shades. So it follows that Scott 122 is MUCH more common, yet in the search for "Denmark 122" in stamps most listings are for 122a (including Anthony's). Go figure.

I was listing some 3c 1861 covers last night and was going to throw one cover into a small batch of low value covers. Markings on the cover indicated that the stamp had an F-grill. I decided to check it anyway despite that very reasonable assumption/guess/identification. I immediately noticed that it wasn't an F and I couldn't decide exactly how many columns of points there were. I decided to take it off the cover and low and behold, the stamp has a D-grill and is a Scott #85, a slight improvement over a #94!

Hi

When I worked in my friend's stamp store, there were many who came in to sell stamps. Of course, all were "rare". One day I was in the store with the other person who was a part-timer also. Someone came in to sell a "rare error" stamp. He was shown a stockbook full of said "error". He commented that the catalog in the library said it was worth hundreds and we did not know what we were doing and stormed out of the store.

A friend that was associated with an expertizing service once told me, if you cannot identify a stamp definitively, assume you have the lowest value stamp.

In all fairness, some stamps are confusing. There are multiple printings with minimal difference between the printings and they only show the picture of the stamp in associated with the rarest first printing which the catalog does not always make obvious. That can be an honest mistake.

Yet there seem to be some people who cannot or refuse to admit to the possibility that they may be wrong. That is a fatal failure in philately and in life.
