The print on the ring finger on the left hand is severely damaged from an old cut. When doing paper prints the lady puts a mark on it stating something along the lines of Scar or Damaged, indicating the print is correct. When doing digital prints last year the machine made me retry 3 or 5 times before allowing me to tell it the print was correct due to scarring/damage. Damaged prints are fairly common is my understanding.

Sorry to hear about your thumb though. Losing that much skin on something you can't help but touch to literally everything sucks.
