Greenstang Posted June 30, 2020 Share Posted June 30, 2020 Don't really see a DDO or RPM. A clearer picture without the reflection may help. The initials are missing due to over polishing of the die, notice how the supports on each end of the roof are also partially missing. If they were completely missing, you would have what is known as a "floating roof". This is common on Lincoln Memorials and has no added premium.
