A very compelling poster was presented at a Met Soc meeting back in
the 90's showing a very plausible scenario that might have produced
meteorites on Earth having come from the surface of Mercury.
Brett Gladman and Jaime Coffey from the University of British
Columbia discussed the possibility of meteorites originating from
Mercury in a 2009 paper from Meteoritics and Planetary Science. A
prepublication copy is available online:

They concluded that there should be a number of meteorites of
Mercurian origin already here -- around 1/3 to 1/2 the number which
originated from Mars.
The Messenger spacecraft should provide better information about the
possible composition of Mercurian meteorites.
David Weir offers a useful summary of the subject of Mercurian meteorites at:
