As far as my own preference, my tools at work are marked. I work all over the plant and as careful as I try to be have lost a couple tools. Fortunately one was marked with my initials, and the other with my name and they were returned when found by honest employees.
My home tools are never lent and not marked.
I've seen comments both ways. It seems like used tools at the flea or pawn are less desirable when owner marked.

I don't mark them, I have bought used tools that are marked, they still work just as good. If the resale price is lower, well then lets deal, maybe I will get it for a song when I buy them.
