I am looking for information to determine if and when Augustine Lawerence Helm's (A.L. Helm) signature appeared on one or more issues of currency. I am told his signature was included on a bill or bills that were printed during his time working at the Bureau of Engraving. He left Hamilton Bank note company in 1885 and joined the Bureau of Engraving from 1885 until 1894 and many examples of currency and bonds produced are of his design. It is my understanding that his signature can be found on some currency produced during this time and I am trying to determine what bils these might be. I am interested in obtaining a bill as an example to present to his great grandson (who is in his 80's) as a gift. Any help would be appreciated. Please post responses here in the forum.
