I assume this is PMD but would like your opinion. Thanks

OldJoe, PMD, the reeding shows some in flat area, it would have been out of collar and clean if clipped, the spreading out into collar is what makes the reeding effect.

Thanks Crazyb0, I thought it may be but wasn't sure. I see what you are saying about the reeding and it makes sense. Why I questioned it is, I thought if it was PMD, there would be tapering toward the edge if a side cutter or such was used. I appreciate your help....as usual.

True, but maybe someone sanded down these areas rather than cutting them. In any case, I agree with @crazyb0 about this being PMD.

Thanks Spence, that very well could be the case. I appreciate your input.

I'm not convinced yet that this is PMD. I do see some Blakesley effect on both sides. I see partial reeding on the edge but only on the reverse rim and note that the reverse is more circular than the obverse. With clips, the metal will flow outward from striking and on small ones could make partial contact with the collar.

On the lower clip (first pic), I see a tapered rim on the southern point.

Thanks spruett001 for your input. I really don't know, just found it odd. Maybe coop will see it and let us know his thoughts.

@spruette, in looking at the OP's last two pics, at least one of these areas is oblique to the surface. I was kinda thinking that a clip would be pretty much perpendicular. Is that a wrong assumption on my part? Just tryin' to learn...

Spence, an edge(straight) clip would all depend on how the planchet stock was formed. Looking at this again, there are two angular "dings"(?) side by side on the rim and also note the rim on obverse is missing going north from "clip", that is damage not an edge clip. Can't think of what would cause this unless intentional...?

I'm not an expert but, my thinking is that the clip is perpendicular before the strike. The hammer die (obverse?) puts pressure on the planchet and the metal moves outward. My thinking is that this process starts from the bottom up, making the reverse side metal move first toward the collar. If so, the slope, or oblique, is a result of the pressure applied. If enough pressure were applied, the coin would be thinner but the small clips would disappear with the increased outward flow of metal making full contact with the collar.

It's the same reason why a perfect crescent-shaped clip will not necessarily be so after striking because of the free movement of metal. I'm going out on a limb but, it makes sense to me.

It is PMD without a doubt, there is no core inversion.
