There have been three variations of the finish on silver LSS wheels. At least there were through 2006 or so. Initially they were to be clear anodized. The very first '05s were delivered with this finish, but the supplier was having a terrible time keeping up with demand as they had a lot of QA rejects. They then went to a satin grey e-coat for the middle of the '05 run until LCU specified the finish that they now have, which is similar to the standard wheels but not exact. The original anodized wheels had much sharper edges on the spokes than the later two variations due to their thicker color coat.
I don't know when the exact changeovers occurred, but it was discussed a lot on here back then. My first car was roughly 300 or so in and it had the duller satin grey finish. I'm not clear on whether they made the changeover to the shinier coat at the '06 model year change or did it as a running change on the '05s.
As to your specific question, I don't think it affects the value one way or the other. Some people might have a preference for specific finishes, but I don't know if it would be enough to affect price. Personally the original anodized would be my preference if given the choice, but there's so few on the market that I doubt you'd be able to pull a premium for them.
