Okay so my first question(picture as well); I am assuming that these notes are not errors and this is fairly common to have a bit of +/- in any direction, but how far is considered an error?
Second question is on the second picture, the left is a series 2013 and right side is series 2009, the reverse plates numbers are very different in size and only 4 bills out of 50 were small. Is this common? I couldn't locate an answer for this.
Thanks!! :)
