It could be just one device is affected because of circulation damage happened. On mint marks, sometimes the mint mark is set deeper into the die than the rest of the other devices. This makes the mint mark taller and a stronger possibilty of being touched while the coin is being ejected. So many things can affect a coin that we don't see. Either bay the same result is just a question and the value is what is marked on the reverse.
