Mint stamp

In philately, a mint stamp is one which is in its original state of issue, is unused, has never been mounted and has full gum, if issued with gum. The term applies equally to postage stamps and revenue stamps.

In practice, the term is used within philately to refer to any stamp that appears to be unused, including those without gum, or previously hinged.

Unlike other collectibles, a mint stamp may be in poor condition but still be regarded as being in mint state as long as it is apparently unused.
