Nice little error! If this was an older series of note, chances are you would see only part of the digit plus part of another digit, hence making it a partial digit error (E16 in the catalogue). On Journey series notes, digits can be way out of alignment but still all visible, so I don't think it can be called a partial digit error. However, the catalogue value of partial digit errors is relatively low, and your note deserves something of a premium even in the condition it is in. I'd give it a tentative value of $30-$40.
