In the pics above, I am looking for the lower D.... which direction is it? North, East, South or West ? This monitor at a remote location isn't the best.

Heh, I have a 5,000 count mint sealed bag I opened up and have a LOT of 1959-D RPM's.
The 1959-D year is nothing compared to the 1960-D year, I too have a bag of those and the amount of RPm's in that one is mind boggling.
Markers are typically set by the people who have identified a RPM, and those markers will assist in finding the correct RPM.
Though these areas might seem common for all the coins, see if there are any others on the coin obverse or reverse.
Identifying RPM's can be a task, or if you have multiple and cannot find an answer, people like John Wexler will do the attribution for a small fee and get the coins back to you as soon as he can - typially 3-5 weeks. I am going to send John a handful of the '59-D and '60-D I have to save my eyes and brain cells.
