LSRNs: 1882 Brown Backs
Brown Backs are among the more difficult types to be found as replacement notes. Here is why. Recall that #1 notes by far constitute the largest percentage of surviving replacement notes. They were the most apt to be misprinted or damaged, and needed to be replaced before shipping to their destination banks. While #1 Brown Backs are plentiful from the pre-1902 era, very few exist from 1903 to 1908, when they were discontinued. Any new banks that formed after 1902 (which would require notes starting with #1) would be of the third charter style, namely Red Seals.
