42 cents (10/2008)
120
my mom who is a postal worker says 2
As of June 10, one ounce of first class mail is 44¢. Every additional ounce is 20¢. So, a six ounce envelope would cost $1.44 to mail, or four forever stamps.
At that size and weight, it would cost $2.20 (as of 2016).
depends on the size and weight Right now stamps are 44 cents for every 10 pages of a normal Business Letter envelope. So if this is 10 pages and LESS you will need one 44 cent stamp. If it is more you will want to put extra stamps on it. Best thing to do take the letter to the post office and mail it if you can they will weigh it and give you an exact accurate weight to mail it. As long as it is in a business envelope, long envelope and not a manila envelope or box. It is that for 10 pages or LESS 44 cent stamp.
If you need to mail 10 sheet of paper, you need to put two stamps on the package. You can fold it in an envelope or put it in a manila envelope.
Depends on a few facts. 1.) The weight of the letter combined with the weight of the envelope! 2.) The shape of the envelope. 3.) The denomination of the stamps......i.e. $0.01 stamps, $0.05 stamps, $0.42, etc. (all USD). 4.) The chemical composition of your saliva (spit) for licking the envelope. For example, if a #10 envelope weighs less than 0ne(1) once, the cost would be $0.42 USD. The number of stamps (you asked "How many") would be 42 if you used $0.01 stamps, all the way up to only 1 stamp if you used a $0.42 stamp This site will explain everything from size to weights. http://www.usps.com/welcome.htm Good luck!
It only takes a single stamp. But it does have to be the properdenomination. Currently the rate for a one ounce flat in the US is 88 cents. (10/2009)
The postage from the US for an ordinary first class letter of 1 ounce or less is 98 cents You can buy a 98-cent stamps or use any combination of stamps whose total value is 98 cents of more. 2 forever stamps plus a 10-cent stamp would work.
If it's a standard size envelope and weighs 30g or less, it costs $1.05. How many stamps that is depends on the value of the stamps. If it's bigger or heavier, it will cost more.
You can buy a full sheet for $4, so you might be able to get $10 for the set if you put it up for sale on eBay.
