What is a commemorative stamp used for?

A commemorative stamp is specifically designed to honor or promote a particular event, person, or significant milestone, often expressing respect or remembrance. This type of stamp usually features unique designs and is issued for a limited time to celebrate anniversaries, historical events, or notable figures.

While commemorative stamps can be used for sending letters, that isn't their primary purpose; they can technically serve that function but are more often collected or saved due to their specialized designs. They may promote events, but again, that is a broader function, and their core intent is to honor or commemorate something significant. The appeal of commemorative stamps to collectors also underscores their role in celebrating cultural or historical significance, but this aspect does not define their primary use. Hence, the central focus of a commemorative stamp is its role in honoring memory.
