Is it possible to chemically remove an entire blue ink background

Resolved Question:

Is it possible to chemically remove an entire blue ink background on a Pennsylvania Duck Stamp while leaving the border and subject matter in their original colors? I would like to know whether the stamp is a printing error or has been chemically altered. It is a U.S. mint stamp with original gum.

Hello, and welcome to Just Answer.

It would be unlikely that chemical removal of the entire blue ink background would successfully leave the border and subject matter in their original colors, plus leave the original gum intact. You might have a stamp with a printing error which may be worth quite a bit. However, this would need to be verified by an experienced philatalelist in your local area, so it would be a good idea to have it seen in person by a professional.

I hope it's worth a fortune!

What is the basis for your answer since I will be asked to provide an explanation? I mistakenly refered to the stamp as a PA Duck Stamp. It is, however, a federal duck stamp.

Hi again,

I was not aware that you had not yet received an answer. I needed to 'opt out' of your question a few days ago, due to illness, leaving it open to all other available experts and placing it back on the 'open question' list. If no other expert has replied yet, unfortunately, I cannot tell you when you may receive an answer.

My apologies,

Hello again,

I'm sorry you had received no additional answers; unfortunately, that's completely out of my control. As I mentioned, I have not been online much, since the 6th, due to illness. I have come online now, to let you know that the basis for my answer was an experiment I read about, a while ago, re: chemically altering stamps (I can't locate the source now, as this was many years ago), and also, what I have read at this website:

As I mentioned, if you can have the stamp evaluated in person by a Forensic Philatelic Investigator equipped with all the necessary tools for testing, that would be your best option to verify it's authenticity.

I hope this explanation will suffice, and I do certainly appreciate your patience, under the circumstances.
