Scott 1326 On White Paper, Hoping To Get More Details

I came across the following:

I have the white paper Scott 1326 (on the right)



I'm curious if anyone knows more about how this might have been made and how common it might be. The Linn's article doesn't give much detail.

Chemical bleaching. And the right stamp you identify as white paper is far from white. Look at the article again and see how white the white paper is. You copy is likely just a sunlight exposure faded stamp.

Here's a better picture. I'll agree it's not as white as the left and right stamps, but it's definitely not gray with the hundreds of threads. If tge stamp was bleached or faded, why aren't the other colors or the design faded?

If I look hard I can see the dark fibers still in the OP's stamp which would not be present in a true white paper.

Sure enough I can also see very faint fibers. Still unlcear as to how the paper and fibers only seem to be bleached out, but not the ink.

Nicholas, two items are a bit off here. First, you ought to post pictures on a black background if you are talking about white paper. Second, you should realize that these stamps are used and me be compromised by the paper they were soaked off from.

Because each color/ink has a different chemical make-up and thus a different chemical sensitivity to light and other chemicals. Some will be quite stable and some quite changeable.

Remembering the R-O-Y-G-B-I-V acronym for the rainbow, it has been shown in many other threads that the red end of the spectrum tends to light-fade much more than the violet.

I fully understand about differences in colors and reaction to water, sun, etc. Just find it hard to believe there is what looks to be zero effect on the ink and design and a high degree of effect on the gray paper and blue fibers. The back of the stamp is identical to the front (not gray and extremely faint fibers). Wouldn't expect fading due to light to affect both front and back at the same time. Note that I'm not suggesting I have anything rare and I'd never claim for it to be so. Just seems that true fading would have more of an effect on the red and blue.

Just going to store it as an anomaly and move on to other items.

I agree this example is not due to fading from sunlight but instead from a chemical solvent that specifically targets the ink in the colored fibers. Not a standard bleach that would affect all colors, but something specific that only affects the blue dye of the threads in the paper.

Another good example of this phenomenon is 1488a the Copernicus with the orange sun "missing". I have an example that I bought with the orange color chemically removed. It is a perfect NH copy with no traces of orange that I can see even under magnification but apparently there is some chemical that can completely dissolve away that one color and not fade other colors in the least.

NicholasC, the article you linked by John Hotchner discusses out right faked stamps changed chemically in liquids to make them look like something that was never produced, right? Now for some reason this thread is going down some rabbit hole about anomalies, misunderstood unequal fading etc.

As John points out these changelings (chemically altered stamps) only occur on used stamps since the chemical process involved employs liquids whci would remove the gum from mint stamps (Thus giving away the fact that the stamp was purposely alter for fraud).

I suggest you read, How to Detect Damaged, Altered and Repaired Stamps by Schmid, Paul W, published by Palm Press 1996.

Parcelpostguy, thanks to you and others for your thoughts. I agree that "anomaly" is the wrong term for me to use. I'm no chemist and so I'll submit to the expertise of others that the paper and fibers were chemically altered and I can use that in the words I keep with the stamp. Can I further assume this is an authentic used stamp that was chemically altered after the fact? or could it have been a mint sheet that was chemically altered and then somehow individual stamps were able to be used as real postage? I'm guessing the former because if the person could alter a mint sheet then that same person could find a way to have it re-gummed.

I'll try to find a copy of the book you mention. Sounds like something I might enjoy reading.

The "How to Detect Damaged, Altered and Repaired Stamps" book is out-of-print. If you cannot find a hardcopy, I digitized it for the author and he sells it on disk. If you need contact info for Paul, let me know.

Thanks Don, would what I see here: http://www.stampexpertizing.com/ebo...oDetect.html be what I am looking for?

Yes, but that is from the old Bill Weiss website I did for him (he was selling it for Paul). https://www.stampexpertizing.com/
Bill passed away but his family keeps the old site up in his memory.

Assume used, then altered; not mint altered, regummed and used. If you have a UV light, you may have fun looking at the stamps with that. Some alterations affect the "UV glow." Some folks add a touch of detergent to the soak water and those often contain optical brighteners which affect UV reaction.

Now one reason you are not getting much "how did they do that" response is because to answer that question, you also give the step(s) for "how to do that."

Now if you want to learn, get some stamps you don't care about, then look for liquids under your sink, in your laundry room and in your medicine cabinet then channel your inquisitive inner-child in a well ventilated or outdoor area. DO NOT mix any product containing chlorine bleach with any product containing ammonia. That can cause human harm or death. And, in general, mixing of different stuff is not needed to make a changeling.

Since we are on "paper changes" be aware that soaking stamps with are attached to colored paper may release dyes into the soaking water and color the other stamps as well as the stamp on the colored paper.

Please consider safety goggles if you are going to play with chemicals.
