New York, New York. $20 1882 Brown Back. Fr. 494. The NB of Commerce. Charter #733. PCGS Currency Choice About New 58 PPQ.A perfect offering of this $20 brown back design for the type or state collector as it shows all the detail one could ask for. Large and even margins house the impression nicely and it appears just a faint corner tip fold at the upper left is all that prevents a lofty Gem assessment. A perfect representation of the Cohen Collection in terms of appeal and desirability.From the Marc D. Cohen Collection.
