I'll buy it. Blakesly is present.

I vote NO....
I don't see Blakesly effect...
and the edge looks grounded in one direction...
... IMHO

Looking at the horizontal lines on the edge, I have to agree John.

COIN HAS A LOT OF HORIZONTAL LINES,BUT DOESN'T LOOK LIKE GRIND MARKS.

My thinking is that the blanking punch would not make horizontal striations, they should be vertical to the field. In most cases of legitimate clips the marks are worn off by circulation, I guess. But, the horizontal lines present on this coin tell me it is not a legitimate clip.

I hope I am wrong about your coin.... but I do not think I am.... here is why...

OK... at the mint there is a machine that cuts round disk that become coins using a punch.. these disks are called blanks or type 1 planchettes as they have no rim and have a 90 degree edge...they go through an upsetting mill.... a curved chamber that is wider at one end then the other.. it applies pressure on the blank using a turning wheel pushing on the blank in a turning method that pushes on the edge all the way around it...
this flattens the edge and makes a proto rim... now it is called a type 2 planchette..

a clip is either a straight clip. formed on the edge of the sheet of metal
curved clip... formed when the punches punch a disk out and then punch another disk out overlapping a hole
or a ragged clip.. a punch at either end of the material where the metal is not smooth on the edge.

your coin looks like a straight clip
So it is the edge of the sheet of the metal material...

now with a clipped blank when it goes through the upset machine...
one side ( the clipped edge ) is not pressed on with the wheel..
This make a proto rim where the wheel touches and NO proto rim where the wheel does not touch... AND no rim on the opposite side.
as it can't press on both sides at the same time due to the void

so with no proto rim to the opposite side... when the coin is stuck you have a flattened area at the rim on that side..not enough metal present to form a good solid high rim
This is called the Blakesly effect after the last name of the person who studied the heck out of clipped coins
Your coin shows no Blakesly effect.. in fact it show damage on that area of the rim.. like some one put it in a vise to hold it in place as they used a belt sander to sand down a straight edge...

the horizontal lines are a question.. IF this was a curved clip.. the punch would leave vertical lines. ( get a new cent,nickel, or dollar and look real close at the edge.. you will see some very fine vertical lines )( this is one way to prove if a missing lettering edge dollar is legit )
being a straight clip.. the metal is rolled out and MAY have horizontal lines.. or may not.. this I don't know as I have not seen a mint sheet of metal rolled out or a straight clip coin.

at the clip area... before the coin is struck... the edge is at a 90 degree to the side...
After the coin is struck the metal will flow into the voided area of the 2 dies..
The clip area tends to slope away from the center ever so slightly..
Yours does not flow outward.. it is 90 degrees..
IF your coin was a legit clip... your metal did not liquify and move at the point of the strike of the coin away from the center ever so slightly
yours also shows what looks like the metal bunching up on the obverse like it has been moved by a mechanical nature.

with common knowledge of the striking of coins and the look of the pictures and the points I made here...
I do not think your coin is a legit clipped coin...
instead I think it was the first or second try at a garage knock off attempt at a clipped coin

If it were a straight clip, my analysis would not make sense. I think I'll stop while I'm behind.

LOL....I was thinking curved clipped also when I said the grinding lines.. but looking at the coin it looks like it would be called a straight clip... these I have not studied as much.. but the science is still the same on the rest of the info presented...

I agree on Not a clip... I also see what appears to be a small remnant of the rim on the obv... The lettering on the rev is not distorted at all at the area in question!!!

Thanks everyone for your commits.Iv'e found many clipped coins,but none with the lines like this one.So I'll send it back to circulation for someone else's collection.

Looks like PMD to me....sorry.
