we cant send if possible means we sould encover through stamps
That depends on what it weighs and where it's going ... not so much on its size. (It could also be related to the denomination of the stamps.)
It depends on the weight of the letter, not where it's going.. The rule I use it, Less than 5 pages one stamp. If the letter is 5 pages or more be safe and use 2 stamps.
The answer will depend on what country you are in, where (in the world) the letter is going and the value of each stamp!
what stamp amount is needed if the letter is 15 oz.?
On a standard letter just one.
One, they print it out at the post office for how much you need (this week).
Going to where? If you mean domestically within the US, then the US Postal Service rate would be $1.90 ... see the Related Links below for more info.
It would be difficult to determine without seeing the item. In general, being on a partial is not going to add any value to it. However, there are specific cancellations and postmarks that might have a value. Your best bet is to educate yourself about cancellations and make a determination on your own.
If the gum gets wet, yes, the gum will get damaged. If you are going to use them for postage, it doesn't matter, the gum will still stick the stamp to the envelope. If they are collectible stamps, you might want to try freezing them, but even that is not going to be a good option. Use of a humidor is another option. Basically it is a closed container with moisture, usually a wet cloth, and don't let the stamps touch the cloth or water.
u need to use usa stamps as English ones are not valied on a letter from America to England ============================================== Postage from the USA to England is 90 cents for a regular letter.
Because it is a way for paying for the mail or letter to get to the other person. That way someone also gets payed to deliver the mail.It was a habit. Before there were postage stamps, there was stamped papers. You purchased them, wrote your message, folded on the lines and the 'stamp' was printed on the upper right corner. The address was going to be in the center area of the envelope, so that area wasn't available.
Some of the variables that might affect the value: Who are they addressed to? Who wrote them? Famous people are going to be of value, normal people, probably not. Normal postage stamps for the era? Or are they high value or foreign stamps? If it is on hotel stationary, it might be worth a $1 an envelope to sell to a collector, but most dealers aren't going to give you half that to carry it.
