What is the value of a Bicentennial Coinage Program quarter that has been printed upside down?

Answer 1

The question is unclear. If you are asking about a coin placed upside-down in a display holder, I wouldn't think that there would be any sort of premium attached to it (above the value of the coin were it placed correctly). If you are asking about a coin produce in medal orientation rather than coin orientation, you would have something very interesting and should show it to a coin dealer for further evaluation. US Coins are produced in "coin orientation" (if you were looking at the obverse of the coin right-side up, and turned it to the reverse by rotating around a horizontal axis, the reverse would also be right-side up) as versus "medal orientation" (if you were looking at the obverse of the coin right-side up, and turned it to the reverse by rotating around a horizontal axis, the reverse would be up-side down) common in some other countries.
