Subject: Invisible property stamps?

Lately I've been reading about map library practices for marking maps,
particularly rare and valuable maps. Once in a while in the literature
there is a mention of invisible property stamps that only show up in
certain lighting.
I haven't met anyone who uses this kind of stamp (or maybe I did and it
is a closely guarded secret!).
Anybody have any comments on this practice?
