Lude Generation

Been looking at the wheels that came on my lude and I was curious to find out how much they are worth (what quality they are etc)? The centre caps say DuLexel and I found a picture of a set of wheels which look just like mine with the same centre caps but the title says they are a rare magnesium JDM only wheel??
Anyone got any ideas or seen these before?

how heavy are they I had a set similar to them on a jdm lude they were uber heavy

I've got a set of Koing E-Racer's off my last car in 17" and the 'DuLexels' are lighter. I'll chuck one in the van and weight it at work.
