How do you find the face value of non-denominated USPS stamps?

Face value refers to the value that is printed on the face of the stamp.

If you have a stamp that has no value printed on it, visit the USPS link, which provides a picture of all the non-denominated stamps and their face value. They are still valid for postage.

The USPS now issues 'Forever' stamps. They are sold for whatever the current rate is for mailing 1st class stamp at the time the stamp is sold. After they are purchased, Forever stamps can always be used to mail a first class letter regardless of the future increases in cost.
