One Dollar Federal Reserve Note series 1969-1999
Main security features of the banknote
Since 1992 1 Dollar Federal Reserve Notes are partly made on roller printing machines. Such notes slightly differ from the banknotes, made by traditional method:
- On the face the check letter and quadrant number near the left edge and the check letter over plate number are omitted (1);
- On the back the plate number is placed over "E' of "ONE' (2);Pictures made by intaglio have small relief;
- small details either are not printed or printed with poorer quality, as a result fragments containing these details portrait, parts of frieze laser work seem lighter colored.
Intaglio:
Light-colored parts of the lathwork on the face and on the back contain black or dark-green small stretched pointed elements (3.1, 4.1). As similar repeating fragments form most of the lathwork, practically the same elements may be found in other places: on the face - in lower part of the frame, on the back - in side parts. In banknotes made on roller machines, such small details either are not printed or printed with poorer quality (3.2, 4.2).
In counterfeits, these small elements have rounded tips, uneven contours, different forms and disposition.

The paper contains imbedded in a chaotic manner red and blue security fibers.
