6 .mn domains with PageRank?

[VisualArtistFrankBonilla]

I have 6 .mn domains which are parked at Sedo, and also have a PageRank. I realize most everybody will consider the .mn extension worthless, but why would they have a Pagerank? I checked the PageRank at 2 different sites. The domains are:

California.mn Pr 3
Dog.mn Pr 3
Mexico.mn Pr 2
Gun.mn Pr 2
Virus.mn Pr.2
Musik.mn Pr 2

These have all been regged in 2007. I also have Maps.mn, which shows P4 4, Dmoz, Archive, but it was regged originally in 1996, and still shows Freemap.com, with a page rank of 617, 537.

Can anyone explain these?

Thanks
Frank

Sometimes when google is doing an update they show a false page rank. That is all i can think of.
