定義

• In the reign of Ed- ward III of Scotland permission was given to Cochrane, Earl of Mar, to coin base money, which were called " Cochrane placks, " and this was a chief charge against him, and for which he was hanged over Lauder Bridge in 1482. The Placks were called in by proclamation after his death.

  This coinage was probably the billon placks and black half pennies (afterwards reduced to farthings). They are said to have been made of copper, and the placks to have been current for three pennies.
