Clip shape isn't always perfectly straight or follow the curve of the circumference (or whatever the original shape of the clip on the planchet was) - the clip shape can get distorted during the strike.

Straight clips often have less Blakesley effect than curved clips for some reason. The Blakesley effect is present here, on the obverse.

Judging from the metal flow of the rim and devices around the clip, this is genuine.

100% - it's a genuine clip. Can't say more than has already been said.
Rest in Peace

Well, I give up, have to take the consensus's view. But...I guess because this is first straight clip I've ever seen, of many BTW, always learning something new.

Still got my contest going, been a-round a few days, still am trying to see why a round die can make a linear cut!

Blanks are punched out off the edge of the blank sheet. Here's a visual of how straight clips happen:

Thanks Mark, that's what I was driving at. There's a curved "die" clip where die actually strikes a stray planchet bouncing in collar, or the straight clip of an off-plate punch error. Two completely separate actions with same name? Its a pre-punch error not POST STRIKE! Now you've made me hurt myself, I gotta headache!

MOOOMMMMYYYY!

I think this is PMD. With a clip the letters in united should be weak and falling off the edge.

Zach can you get a picture of the edge of the clip area? While the rims look tapered the people that are seeing metal flow and weak devices I mean Ido have bad eyes but I just can't see any metal flow or device weakness but I've seen clips with minimal. I'd like to see what the edge looks like myself

Huh?

The metal flow is along the base of the lettering.

Just have to remember all clips don't follow the same rules or guidelines. Size of clip, where it was clipped, and shape of clip are all determining factors of the final result.

Responding to Errorcoins222, what I meant that a "straight" clip is actually pre-die-press state. Once cut from sheet planchet is first "prepared" by forming the raised and finished edge...then goes to the presses. It is "clipped" in the sense of a "pressing cutter". The "curved/parabolic" clip is indeed "cut" by the downward motion of the round edge of the obverse die, but...one could be considered a pre-strike error(straight), the other (curved) is during the strike or at rare instances post-strike if "floating around", such as a partial one side edge clip, got a couple of those.

Confusing only in linguistic definition of "clip", not precise like other languages. I will call all "clips" from now on!

Clips are formed when the blanks are punched out of flat stock. The dies have nothing to do with creating clips. They can be curved, straight, or ragged.

The correct term is incomplete planchets. But referring to the area, it is referred to as the clipped area.
