Si'
Come si spiega su internet, ''air mail stamps are all valid for postage. All postage stamps issued by the United States since 1860 (con limitatissime eccezioni), are valid for postage from any point in the United States or from any other place where U.S. Mail service operates''. Come spiega l'azienda postale degli Stati Uniti (USPS) , ''U.S. postage never expires; you can use existing stamps indefinitely. All postage stamps issued by the United States since 1860 are valid for postage from any point in the United States or from any other place where U.S. Mail service operates. You may use any Denomination stamp(s) to equal the total postage affixed. Total postage affixed must equal at least the postage charge for the class of the mail''.
