Penny \Pen*ny\, n.; pl. {Pennies}or {Pence} (p[e^]ns). Pennies
   denotes the number of coins; pence the amount of pennies in
   value. [OE. peni, AS. penig, pening, pending; akin to D.
   penning, OHG. pfenning, pfenting, G. pfennig, Icel. penningr;
   of uncertain origin.]
   1. A former English coin, originally of copper, then of
      bronze, the twelfth part of an English shilling in account
      value, and equal to four farthings, or about two cents; --
      usually indicated by the abbreviation d. (the initial of
      denarius).
      [1913 Webster]

   Note: "The chief Anglo-Saxon coin, and for a long period the
         only one, corresponded to the denarius of the Continent
         . . . [and was] called penny, denarius, or denier."
         --R. S. Poole. The ancient silver penny was worth about
         three pence sterling (see {Pennyweight}). The old
         Scotch penny was only one twelfth the value of the
         English coin. In the United States the word penny is
         popularly used for cent.
         [1913 Webster]

   2. Any small sum or coin; a groat; a stiver. --Shak.
