To the best of my knowledge, only $1 notes are part of this variety.
James has a very valid point: the FPN "11" is extremely difficult to read with the naked eye. I can usually read it, but I have to look at it carefully. I usually cheat and pull out my loupe.
The back plate numbers on many 1954 notes are blended into the design very tightly and are thus very difficult to read, even if you know where to look.
