A meal is usually a coin-like sculpted object of metal or other material that has been engraved with an insignia, portrait or other artistic rendering. A medal may be awarded to a person or organization as a form of recognition for athletic, military, scientific, academic or some other kind of achievement. Medals may also be created to commemorate individuals or events or even as works of artistic expression in their own right. There are also devotional medals, which may be worn as a matter of religious faith. Medals are popular collectable items either as a form of exonumia or “paranumismatica”, or of militaria phaleristics.
