This is a circulated 1995 $1 note with the rare B X block serial number.  

B 10785239 X

In addition, the right serial number has a shifted digit. Unlike most shifted digits that are "turned," or slightly raised or lower, the 8 is shifted to the right, giving a noticable space between the 3rd and 4th serial number digit.

The note has one corner with a heavy fold and a small margin tear. Please review the photos.

Thank you for looking.
