Removing the cancellation from a United States Postage stamp for the purpose of reusing it is illegal and constitutes fraud. It is a federal offense. Just pay the 44 cents!

It depends on the time frame of the stamp. If there is a special cancellation, you definitely want to leave it on the cover. The older the piece, the more likely the cancellation and date will be of value.
It isn't the stamp, it is the cancellation that makes a First Day of Issue. And what you will have in the US is a cancellation that has two bars top and bottom with the words First Day of Issue in between. The bull's eye will be on the left side with the city and date on it.Many countries include some related picture in the cancellation. Ideally the cancel will clearly 'tie' the stamps to the cover, making it obvious that the stamp was on the envelope when the cancellation was applied.
It depends a great deal on the stamp and how old it is. If there is a special cancellation or cachet on the envelope, it is better to keep it on the envelope. The older the stamp the more likely that the envelop will have more value than the plain stamp. It is better to leave the stamps on the envelope because there is a postage mark that goes over the stamp. That will give the stamp more value.
Scott US#1270If it is a first day of issue, it should have a cancellation. A First Day Cover is likely to be worth about a dollar. Without the cancellation it is worth the same as a used stamp, about 15 cents.

That depends on how it is dated. If it is part of a stamp design, it might be much newer and celebrated an anniversary. If it is a cancellation, it might have some value. Consult a good stamp catalog to identify the specific variety.
Post offices experimented with precancelled stamps in an effort to reduce work load. Supposedly these stamps would not have to go throught the cancellation machine and eliminate that step in processing. The city and state the stamp was sold in was printed on the face of the stamp. This also made it difficult if someone stole the stamps to resell them in another place.
No, a postmark is a marking on a letter or package indicating the date and time that the item was delivered into the care of the postal service.This is put on after the stamp.
This term means the stamp has no tears, no holes,no thin spots, no creases and no missing parts. It does not say anything about the centering , the gum or cancellation. If the stamp has missing corners or missing perforations or stains, I think should be mentioned if the stamp is described as sound.
The word cancellation is the noun form, a word for a situation in which something that has been arranged is stopped from happening; an act of officially ending a legal agreement or responsibility; a mark on a stamp, a check, or other document showing that it has been used.
