As the highest denomination for Series 1950E FRNs, the $100 notes are the toughest. While a district such as New York was printed in sufficient quantity, a smaller district like Chicago—with about one half million printed—will be tougher in the higher grades. Stars were printed for only two districts—New York and San Francisco—and in very small quantities. Higher graded, uncirculated examples of these will undoubtedly be the challenge with this set.
