So, what is a first-day cover?

The three basic elements of a first-day cover are the envelope, the stamp, and the postmark. The postmark is the critical element as it verifies the date on which the stamp in question was canceled and ties it to the cover. If the date of the cancellation is on the first day a particular stamp design has been issued by the post office, the envelope it is on is a first-day cover.

Generally, the US Post Office issues a stamp in only one city the day before a new issue is put on sale in post offices around the nation. The issuance of a new stamp is frequently a cause of celebration, and as such the post office often holds special ceremonies in the first-day city.
