wow great thread. If i owned that 77D gbroke posted that coin would be buried with me , man one heck of an IKE. You don't see those colors on Ikes and its no doubt NT.
There is no S/S 1974-S IKE. What folks and many numismatists and graders assumed was an RPM actually turned out to be a doubled Mint Punch which also exists on the 1976-S Washingtons, Kennedy's and IKE's. A true RPM would not exist across coin series much less coin years.
Acquired after starting this thread, photo doesnt show it but this coin has a golden hue on both sides
Wash used on 1973 & 1974 40% Silver was a new mix books note. Some say that why population of PR 69 Ultra Cameo are low.
This is a good topic by itself the 74s in my boxes among them are some of these variants. They don't seem to have any premium but are interesting. I don't want to hijack this post with a lot of non toners so I will post em in another post.
