bus medal sports metal-Traditionally medals are stamped with dies on a durable metal flan or planchet, or cast from a mould. The imagery, which usually includes lettering, is typically in low relief, albeit often higher than on coins: Limited-edition medals may be struck in repeated impacts allowing more metal displacement than in coins produced for mass circulation in a single impact. Circular medals are most common; rectangular medals are often known as plaquettes. The"decoration"types often use other shapes, especially crosses and stars. These in particular usually come with a suspension loop, and a wide coloured ribbon with a clip at the top, for attaching to clothing worn on the chest.
