The pegleg on 72-S proofs is a "Design" pegleg, thus, normal true die state, and not an abraded one...All IKE S-Mint coins were struck 2, maybe 3 times at the mint, for exceptional detailing, thus, we always find SOME sort of doubling on most mintmarks and letters...many Master Hubs and Dies were doubled, thus, the working hubs and working dies picked up the doubling, and, it is considered(Wexler, Wiles, etc...) a non-attributable double die...many IKE listings for
DDO /
DDR have been "Delisted" by attributors as Master Hub, or, Master Die Doubling...the entire IKE world
DDO /
DDR situation is changing weekly, as 3 major "Schools" of thought emerge from the conficts...some believe the
DDO?DDR's should be listed as "Families", with similar notching in the same serif locations, strong to weak....others believe "Hub #'s" should be used for classification...bottom line? If you sent the same possible
DDO to 5 different people now, you would get 5 different attributions...varying from "No-Premium-MDD", to true
DDO, say, FS-101....it will be interesting to see where the dust settles, and, which classification system wins out for top Numatisists. I don;t know of ANY other denomination of USA coinage in such flux...it's a fun time too, because new findings lead to new theories on IKE Dolllars..mint records show some working hubs were "Promoted" back into Working dies, creating a bog of messiness too.
Throw in
Machine Doubling, and Displacement factors, an IKE can show 3 different movements on 1 coin...complicated? Yes. Hold onto your seats, and keep your coins until we know more. I am developing my own theories on all of this, and, infantile as they are, someday, I hope to write an article on my thoughts, for what their worth.
I can't tell you HOW many times I have sent IKES in, with Strong doubling, only to get them back as Master Die issues, and, no premium....I'm trying to memorize the MDD notching, Vs. true doubling notching, it's TOUGH!
