stamps with no price on them

[Vicky]

I have some stamps from last year (I think?) but they have no denominations on them. How do I find out their value

(I dont want the post office to return my letters due to insufficient postage)

This site from the USPS is useful it shows stamps without denominations and tells you their value

QSG 604a Basic Standards for All Mailing Services - Nondenominated Postage

hope this helps!
