The first $1 notes (called United States Notes or "Legal Tenders") were issued by the Federal Government in 1862 and featured a portrait of Secretary of the Treasury Salmon P. Chase (1861-1864).
The first use of George Washington's portrait on the $1 note was on Series 1869 United States Notes.
The first $1 Federal Reserve Notes were issued in 1963. The design, featuring George Washington on the face and the Great Seal on the back, has not changed.
Of all the notes printed by the Bureau of Engraving and Printing, the $1 note makes up about 45% of currency production.
If you had 10 billion $1 notes and spent one every second of every day, it would require 317 years for you to go broke.
Faceplate Numbers and Letters are the small numbers and letters that can be found in the lower right and upper left corners of a bill. In the left corner is the Note Position Number. This consists of the Note Position Letter and a quadrant number. The combination indicates the position of the note on the plate from which it was printed. In the lower right corner, the Note Position Letter is followed by the Plate Serial Number. This identifies the plate from which the note was printed. The Plate Serial Number for the reverse (back) side of the note is in the lower-right corner, just inside the ornamental border on the reverse of the bill.
