I've managed to reunite an interesting pair of $20 Plain Backs from Salem, OH, Charter 43. Both were acquired in Baltimore from different dealers about 6 months apart. So far these are the only two PBs with Lyons | Roberts signature combinations or Fr. 650 and dated Apr. 11, 1902 just like charter 43 date backs. Other $20 PBs that I can find have Speelman | White signatures or Fr. 635 and are dated Apr 10, 1922 (note: Track and Price doesn't identify the Fr. #). The Serial numbers are 5226/V967960B (back plate 325) and 5227/V967961B (back plate 315). Both are from A plates as are all $20s on Ch. 43 notes. Now, why would the back plates differ? A prior owner submitted these two notes together to PMG. I like these notes because of the low charter number, interesting Fr. # possibilities (rarities), pretty penned signatures of bank officers W.F. Church and Z.R. Pow, sequential serial numbers (of course) and in the exact same grade of 30EPQ. Let me know if you owned these before, or if you have any insight into why the back plate numbers would differ.
