I am going to go ahead and say no this is not a clipped planchet it appears to me to be PMD but I'm going to ask the group ya'lls opinion. I don't see a Blaksley effect, I see upset of the rim from possibly a file and there are many "clips". 5 to be exact along the rim which makes me think at some point someone was trying to save some silver, I however have read that not all clipped have a Blaksley effect.
I don't think that it's a clip. The angle of the arcs there don't fit with a half dollar, but hard to tell without measure.
