?Authentic Motorsports? How do you tell?

[BLOODBOUGHT]

Can somebody give me a clue...how do I tell if my 17" motorsports are authentic or replicas? If they are authentic how much are they worth (ball park)?
Thanks guys.

There should be a BMW part number on the wheel if the are original. As far as price goes, I am not sure, too many factors involved.
