spotted this coin which looks like it has a clipped edge, but it still looks weird to me. thoughts?

PMD, reminds me of being linked together (or planned to) with other coins for jewellery or something, but with Aluminium coin maybe it was just an experiment before working on silver coins? Definitely don’t think it’s an error, maybe it was just put and squeezed in pliers.

I was thinking something like it being squeezed but I can'r see the beads where they would be, and wouldn't it bulge outwards not inwards? Looks too cleanly done to have just been squeezed with pliars

It is after all aluminium, the pliers could just take the metal with them I guess?

I don't think it's PMD, because it looks like you can see the Blakesley effect you can always see with clip errors:

It isn’t really a clip though is it? All I see is that the rim and dentils have been removed, you can still see the metal where they were because whoever, however it was done, have not completely removed or smoothed the metal to the level of the fields.

Seems like it could be.

 

And this bit here I have never seen on a clip error.

it just looks like it has been filed.

It looks like on my clip error (although not as much, but on mine also a part of the rim is gone, further than the end of the clip error (see blue arrows). The red arrows show the Blakesley effect:

I agree it's only a small clip (smaller than I normally see). But the clip is also curved, not flat like your red line suggests on the top picture. And what looks like the Blakesley effect is right on the opposite side, where it should be. That can't be a coincidence. I still believe it's not PMD but a small clip error.

Wow I am learning way more about clipping errors than I thought I would, I never knew of the blakesley effect, is this something that happens on all clipped coins or most or few? Even if it's only a small clip I should keep this coin seperate from the others (I received many of these coins all at once)

My red line was not suggesting any shape, but the missing rim and dentils shaved from the coin part which hasn’t been removed.

 

So for example on your Belgien coin, the B E L would be shaved away, but it isn’t. So why is the rest of the rim and the dentils missing on the OPs coin? (In the red line, which is still part of the coin) that is the bit I have never seen on a clip error coin.

Agree with the clipped planchet error observation as I have a few clipped coins with the exact same effect on the opposite side of the clip defect. When stamped in the press the planchet shifts as it does not seat perfectly, shifts and distorts both the voided area and the area opposite the void. Thats the best way I can explain what goes on in a fraction of a second under relative tremendous pressure. Aluminum in this case.
