Its obverse has featured the profile of President Abraham Lincoln since 1909, the centennial of his birth. Since 1959 (the sesquicentennial of Lincoln's birth), the reverse has featured the Lincoln Memorial.

The following types of cents have been produced:

Answer 2

Usually a King or Queen. Pennies are/were used in Great Britain and some of the British Commonwealth of Nations. In the United States we have cents and it takes 100 to make a dollar. The list by Shellbugg looks okay to me. One other little tid bit of information, cents have been made every year but one and that was 1815.
