If the note is the same size as the other you have, then this is most likely a Cut out of register error, but a very minor one.
This occurs when a mote is cut improper alignment of the sheet. The greater the misscut the greater the value, and usually part of another note must show to result in a premium value.
The note shown does not seem to show another note at the edges. There would be very little premium in the note. Still interesting, and worth a little over face value.
Hope this helps
