Not super strong but it makes the grade, if only just.  I am sure that that was lightly cleaned a VERY long time ago, as found on probably 95% of all survivors.  This is based upon my experience with the series as it is not obvious, with no obvious hairlines and good color, what would be considered 'normal' in terms of the coin market.  Certainly most dealers would not even mention the possibility.  The price has been adjusted slightly however, for the very minor problem.    1212-14
