Ok, after about 8 hours of well deserved sleep. My brain is below boiling once again.
I have shot pics of all the 1961-D RPM's I have and here is another I am currently researching.
I don't know about anyone else, but I like to attribute my own coins, and then try to match them up against sources. Some of these websites, the pictures are horrible.
Enough said.
The first 1961-D/D (or better) shows a strong upper and lower split serif;



This next picture has TWO markers.
On the Top Right of the Memorial building and travels down the last column.

The "C" in AMERICA has a significant die chip.


The Die chips shows on 7 of 9 examples


The Extra metal on the building is on 9 of 9 examples - some are weak.


The last thing I could find on all 9 of 9 coins is that the top of columns #5 and #6 are washed out pretty badly;

I am currently search through all the coppercoins examples, and I'll report if I find a match.
