Nice find. I'd still keep it even though it maybe be one of the Working Hub Doubled dies. Wexler reveals This information on his site:
Quote:Significant changes have been made to the 1966
Kennedy half dollar obverse doubled die listings due to the discovery of three different obverse doubled working hubs.
http://doubleddie.com/1141429.htmlThe reassignment of numerous 1966
Kennedy half dollar obverse doubled die listings as being from the obverse doubled working hubs left huge "holes" in the obverse doubled die listings for this date. As an example, there were once 37 listings for the 1966 obverse doubled dies. Now there are just 12 working dies and the three working hubs. Many listings were assigned new numbers in order to fill the gaping holes in the listings. Notations of these changes are made for each of the affected varieties.
What does that mean? While they are showing hub doubling, the problem is that the hub was doubled, so technically they are not doubled dies, as the doubling was on the hub. There are a few examples of doubled dies that were created on a die that had hub doubling. But I would save these for now. I'm not buying any as the value may just bottom out, or something else may happen? Who knows. But Evidently the something must be up as several of the listings on Variety Vista doesn't have images anymore. So time will tell on these for their value. They may just be listed by their WWHDO-001-3 numbers in the future. But Wexler has removed many from his attribution lists and have replaced them. CPG has not noticed this yet.
