Collecting Covers - A Stamp Collecting Specialty

New stamp collectors may wonder just what "covers" are, and why they are collectible.

The most simple answer is that a "cover" is an envelope that has been stamped and sent through the mail. They can be collectible for the stamp(s), for the postmark, for the recipient or for the sender, or a combination of these factors. There are two main types of covers: commercial covers and philatelic covers.

Commercial covers are those that are mailed for ordinary (non-collecting) purposes. Since by definition they are not created expressly for stamp collectors but are instead used to transmit material (whatever was inside the cover) they always contained some type of content (although that content often is removed by the recipient before the cover gets into a collector's hands).

Philatelic covers, on the other hand, are covers that are created and mailed specifically for the purpose of someone collecting them. Sometimes they originally include(d) some type of meaningful content inside, but other times there may only be a blank cardboard stiffener. First day covers are a subcategory of philatelic covers.

Sometimes the distinction between commercial covers and philatelic covers can be a bit blurry. But if you're a commercial cover collector, it is essential to be able to determine if a particular cover is commercial or philatelic.

Tomorrow we'll discuss how many stamp collectors make this determination.
