(Scott Specialized Catalog of US Stamps 2011, page 394)
The US issued a Chester W Nimitz stamp.
That stamp was issued in 1985. It has a face value of 22 cents.
The F series stamps were issued in 1991. The postage stamp has a face value of 29 cents.
can anyone tell me wow much it is worth\ the stamp was circulating in 1957 or 1958
It is worth the original cost of the stamp.
These sold for 33 cents and are still worth that amount as postage. You can only use them for postage for destinations inside the US.
It depends on the stamp which you have. Although, to be honest, most stamps issued this recently aren't worth very much. Generally, since there were so many printed, it is used as postage on mail!
That depends on many factors. A stamp is worth its face value for use as postage. If you have something that is old and is rare, it could be worth some money. Today's First Class postage stamps are 44 cents.
It is worth 15 cents.
This stamp is called an F makeup. It is worth 4 cents. It was issued in 1991 along with the F stamp which had a value of 29 cents
The stamp-postage value of a stamp is visible on the front of the stamp.
This would depend on what year it was issued and the condition of the stamp. For example a used stamp in average condition from 1998 is worth between 6 and 19 cents to a collector but could not be used for postage. An unused stamp in average condition from 1998 would be worth face value; in the case of a forever stamp (without a face value printed), it would be worth whatever the current postage rate has been raised too (as of January 2013, it would be worth 46 cents) and could be used for postage at that value.
