Other philatelic collectibles include:
* Plate Blocks usually consist of four stamps from the corner of a pane, with the printing plate number in the margin (or selvage) of the pane.
* Copyright Blocks feature the copyright symbol © followed by "United States Postal Service" or "USPS" in the margin of the pane. The USPS began copyrighting new stamp designs in 1978.
* Booklet Panes are panes of three or more of the same stamp issue. Panes are affixed inside a thin folder to form a booklet. Usually, collectors of booklet panes save the entire pane.
* Souvenir Sheets are panes of stamps issued without plate number's that may have margins containing lettering or design that commemorate a notable subject, such as Daffy Duck and Sonoran Desert.
* First Day Covers are envelopes bearing new stamps that are postmarked on the first day of sale. For each new postal issue, the USPS selects one location, usually related to the stamp subject, as the place for the first day dedication ceremony and the first day postmark. There is even an annual First Day Cover Collecting Week.
* First Day Ceremony Programs are given to persons who attend first day ceremonies. They contain a list of participants, information on the stamp subject and the actual stamp attached and postmarked.
* Matted Panes are full panes of stamps that are on a colored matted sheet to match the stamps. These are suitable for framing.
