Here are three coins, same year, same type.
Reverses of this three coins are in the same angle.
But when I turned over them, some alignment problems happened.
As you can see, I put a ruler on the ''O''(or the nose), the coin number 3 has the higher ''O''(or the nose) obviously.
Alignment matters? Is't one of the strict measurements to decide whether it's the real one?




Any suggestion?
