1968 Or 9 D Washington Quarter. DDR? Clipped?

Cool coin! : )

In my opinion this is just a clipped planchet. The "Grease error" you are seeing on liberty is actually not caused by grease. This is called the Blakesley effect. During the rimming process the clipped planchet has a weight difference on the opposite side of the clip which causes this effect. This helps identify PMD over a real clipped planchet.

As for the "doubling" you are seeing: when a clipped planchet is struck by the die, the metal around the clip flows towards the clip which is what you see. The design elements are flowing towards it.

The clip occurs before the strike of the die, when the planchet is cut. It is then rimmed, then struck. Looking at a clipped half dollar I have it shows the flow of letters on the reverse only as well. I'm thinking this might only happen on the anvil die and not the hammer? But that's just speculation on my part.

Here is another clip recently posted here that exhibits the same reverse only flow of design elements: https://goccf.com/t/219010

Ok I kind of suspected it may not be a clip with the raised metal along the line of the clip in question. So Super Dave what you are saying is the larger the clip the stronger the fading is opposite if the clip? I'm just going off what you said in regards to the fading on Liberty. So if it isn't a clip what are the chances on the DDR? Best 1 out of 2 haha!

Sorry, I knew I had seen some of these straight clipped planchets before. So the planchet was cut from the end of a sheet of metal.

Looks a lot more like this: http://www.error-ref.com/_straight_clips_/

This is absolutely a genuine straight clip, nice find All of the correct diagnostics are present- tapered rims at the edge of the clip and strong die flow on the devices at the edge of the clip.



The Blakesley Effect is primarily created during the rim upsetting process, not during striking. The rim upsetting process involves force-spinning a coin through a narrowing channel which slightly reduces the diameter of the planchet and forms the initial proto-rim. If the diameter starts out smaller than it should be, then the force applied to the planchet is not as great and the proto-rim is either weak or nonexistent which results in noticeable weakness of the rim on a struck coin. The Blakesley Effect is also typically weaker on a straight clip than a curved clip. Given two clips of equal volume, one straight and one curved, the curved clip will have a stronger BE(weaker rim) because the diameter measured at the center of the clip will be smaller on a curve that it would be with a straight edge.

I think the "pinched edge" is a bit of an illusion with the lighting in the photos, sometimes I see it as pinched after SsuperDdave brought it up, but most of the time I see it as a partial rim. More pictures of the rim with colder lighting than the first images but warmer than the last ones would show this more clearly.

But then again, if it is pinched and not a legit straight clip, why does it have symptoms of a clipped planchet? You can't fake die flow can you?

I am willing to come to your way of thinking, if you'll tell me that planchet strips have beveled edges, and straight clips can have a fully-formed rim to the edge of the clip. You can use this one as an example for me:

I'm not afraid to be wrong, nor to admit it. I've learned more from you guys than you have from me.

I'll buy that; I'm not the world's foremost expert on planchets.

But I *do* know my way around rolled sheet stock, and it ain't beveled from the factory. If it's a clip, that beveling somehow happened during the strike or the prep.
