Is the five dollar bill worth more than five dollars?

Answer 1

Not yet. If it contains any errors, it would/will be.

More...There is an internet rumor / urban legend that the new purple and gray $5 bills have the "wrong date" because they show Series 2006 even though they were printed in 2008. But the date IS correct because a "series date" doesn't indicate the year a bill was printed - in modern usage, it's based on the year when the serving Treasury Secretary took office.

Because Henry Paulson was Secretary of the Treasury from 2006 to January 2009, all bills printed during his tenure (and even some printed afterward as part of a given run), both the new bills and the old green and black ones, have the same series date.
