OP.
THX for coming back around!
The crap/scratches/stuff on the right side of the holder almost looks like tape residue, dirt or spilled and dried soda pop (or glue of some sort). I don't think it's on the note. You can try to remove whatever it is by using a cotton swab with a little bit of alcohol on the tip and then gently rubbing the affected area of the holder with the alcohol dampened cotton swab. Don't over do it.
Looks like a nice note! Good luck!
