First off before you open the spoiler to reveal the grade look closely and think about the grade you would give it and post the grade you would give based off of the cover alone.
Trust me even if you opened the book and rays of sunshine sparkled out you'll never think the inside would give it this much of a bump!...
So you were given credit, not actual money, for the FMV of books they lost?
I'm hoping these were new, off-the-shelf moderns, or you were given a choice, as being out $1000 of books and receiving $1000 of credit is not the same.
