The 1955D cent appears that it could be 1955D-1MM-002, a real RPM. It may also not be, it could be Machine Doubling with odd lighting. It would have to be examined or photographed better to tell for sure.
The proof coins with the "ghost" letters are rather common. They are sold at a premium, but I question their long-term status as something worth that premium. I personally would not be in the market for them.
