Well, actualy a typical signed autograph wouldn't be worth much actually, also depending on weather or not it is framed etc. But since it is the 1998 broncos autographed i would estimate that it is around 780 dollars at this time. :)
The value depends on a number of things: 1. What year/season is the signed football from? 2. Whose signatures appear on the ball? 3. What is the condition of the football and the signatures on it? Once you answer these two questions, you can begin to have a notion of the value of the football.
What is the value of a box of Wheaties. Denver Broncos 1997 champions. Full in perfect condition.
On paper or other item, usually $5-10 $5 to $40 on a football trading card depending on the card.
