A blank planchet is fed in between two dies (and inside a collar). The dies come together and strike the coin. Both sides are struck at once. (It would be impossible to strike only one side. Equal and opposite reaction thing.)
But if TWO planchets get fed in at the same time you can have two one sided coins. (one of them will also be a partial collar, and neither of them will be flat and smooth on the blank side.) This does happen but it tends to be very rare.
Absolutely. And both newly-struck one-sided coins will have been struck on the blank side. (They will have been struck by the blank face of the other planchet.)
... I have looked through about 17,000 cents and never found any error like that.
