Splash Striking. Striking medallic items in a press with no collar to restrain the outward flow of metal between the dies. In one case a somewhat oversize blank is used and when struck the extruded metal from between the dies merges with metal of the perimeter of the blank that often forms a slightly buckled border. In another case a blank with a purposely irregular shape is used to form an indistinct, irregularly shaped, slightly raised border as intended. Normally such extruded material when struck without a collar -- called flash -- is later removed by trimming.

In America splash striking applies only to the use of coinage dies without the collar to strike such pieces. In England splash striking has a wider meaning. It is a term for all striking with open face dies. Not only is the term different but open face dies are called box dies in England. See open face die.
