The cost of a United States first class stamp in 1969 was six cents. United States Postal Service rates have been relatively unchanged until 1968. The price since that time has increased every few years by a small amount. The stamp itself is a small adhesive piece of paper with the specified value issued by a postal authority to be affixed to a letter or a parcel to indicate the amount of postage paid.

People put stamps on letters so the post office will post (mail) them. The money which is spend on stamps helps to pay for the post offices, the vehicles (vans), and post men and women who deliver the letters for patrons. The U.S. first class stamp now has different pictures on the stamp to help with popularity, to note important historical events, and to honor iconic people. The U.S. first class stamp is the most commonly used stamp and currently has no fixed amount of postage noted on its face. This stamp is called the USPS 'Forever Stamp'.
