What is the value of 1985 one hundred bill?

It could be worth as much as a hundred dollars. However, if the corners are bent it would only be worth ninety. Also, if there is a crease through Franklin's face it would only be worth eighty.

To be serious, there is nothing special about a 1985 100$ bill. Take it to your bank for a new copy or put it under your mattress. It might be worth something in fifty years.
