In the last 2 months, 3 new 1859 Narrow 9 die pairs have been discovered by 3 different collectors. In the next few weeks, these will be added to the Haxby on line catalog. (I'm hoping to get the first one on this weekend) 2 of these pairs have new reverse dies and one is a new pairing of known dies. This brings the total of 1859 N9 reverse dies found to 225.
Keep hunting. There are more discoveries out there waiting to be found!
