What is the value of a 1989-P US half dollar with two mint marks on the back?

If the "mint marks" on the reverse are the letters "F" and "G," then these aren't mint marks at all, but the initials of Frank Gasparo, the designer of the half dollar's reverse. In that case, you have an ordinary 1989-P half dollar, which will run between $1 and $90, depending on the coin's condition, as of May 27, 2007. If the "mint marks" on the reverse are something else, then your coin is best evaluated by a professional coin dealer who specializes in error coins.
