*** Edited by Staff to Add Year / Mintmark / Denomination to Title. Titles are Important! ***There are no stupid questions, there are no stupid questions...
I believe this is MD but looking at some of the references the pictures for legit
DDO sometimes show flat doubling.
My main question is about the mintmark, was it applied by hand using a punch and hammer?
If so, from what years until it was integrated into dies?
This one looks as thought another tilted "D" is inside the top "D".
I am trying to understand why the OMM, RPM, etc and how they all happen.
