Definition

• Coining Dies.  Specially prepared working dies intended for use in a coining press which produces a struck piece – coin or medal – with a single blow, including some form of edge treatment. Coining dies are made from very low relief (bas-relief) models and are always used in a coining press with a collar which will produce a smooth or reeded edge. Since coining dies must fit within a collar, they are also called collar dies. In very rare instances medals struck with coining dies without a collar, forming indistinct borders, is called splash striking (q.v.).
