I have it at least MS65 because of stunning luster and eye appeal, but I thought it could possibly get MS66.
The carbon spots do bother me though. I almost consider them a "problem" and I just can't stand it.
As far as value goes, if it's at MS65 I would still have to put it higher than $50 because of the toning. Now what that value is I don't know. There are some buyers that put a big premium on this type of toning. Granted, it is a Jefferson and not a Morgan.
