Old newspapers that cover events of national or worldwide importance may be worth money to collectors. For example, major events that increase the value of an old newspaper may include the bombing of Pearl Harbor, D-Day coverage, reports on the Battle of Gettysburg, and the assassination of John F. Kennedy.
Historical newspapers from dates with no important events may also be worth money, depending on their age and condition. These papers are referred to as "atmosphere" newspapers because they provide a sense of the past despite their lack of major event coverage. Early papers that carry engravings from important artists may also carry additional value.
