Just wondering if this great forum can help my brother. He has aquired a 1912 Train note graded VF25, its series B seal only DC-21f . Where can he check for value and population is there a registry online that he can see this noted registered? We have checked the latest Charlton book and the serial numbers C651343 do not seem to match up with the range that it says it should. We are just beginning to learn and collect these wonderfull old notes so any help is mutch appreciated
