I found this 1974-D Kennedy while CRH yesterday. I looks like it was clipped a small amount at roughly the 12, 3, 6, & 9 o'clock positions. Any thoughts? Thanks.
Interesting. I know of Triple Clipped Planchets but not Quadruple Clips on a Half. I'm thinking the lighter looking (clip) at 6 o'clock could be just the Blakesley Effect. . . . . By the way. Here is a Triple Clipped from my collection -
Anyone who knows more about the planchet punching process... can a quadruple clip even happen? From what little I understand, a triple would be the most that can occur...
It looks like somebody was messing with it on a grinder. I do not believe it's a quad clip for the following reasons * The edges of the rim next to clip are full. If the planchet was clipped, the metal would not flow up into the edge, completely filling that small area of rim when it would be less resistance for it to flow into the void space. * It looks like the scratches along the "clip" follow the edge. Any marks left from punching would be vertical (Obs to reverse). * I also don't see how you could have 4 equally spaced, tiny clips coming from the blanking punch. As the sheet goes through the machine, rounded clips come from misfeeds. How could there be a big area of metal with that has been punched on all 4 sides (small clips) and then have a blank punched out from the middle. I cannot see that happening in production.
The only way I think it could happen is if it's struck on the scrap part of the sheet, in which case would result in 4 very large clips
The view of the edge in the 3rd image doesn't look like a clip. Note that the thickness is uneven and expanded at the point of the presumed clip. I think it is PMD. Chris
I was thinking it was cut at those specific points to put in some kind of jewelry. (Belt buckle, something.)
The clips shown in the photo's are NOT valid clips but PM alterations IMO. Understanding the gang punch operation is critical in determining the authenticity of a curved clip (concave) on a CnClad coin. Since the blank is gang punched from a CnClad strip, the cladding is forced up over the edge of the blank. This is what accounts for the half copper/half clad edges on these coins. If you address the CnClad strip as Top and Bottom, as the punch gets forced onto the top of the strip, the top cladding gets stretched over the edge of the bottom of the blank while the strip itself gets the cladding stretched over the top of the hole. What this means is that the blanks will be the exact opposite of the holes in the strip. So, looking directly at the clip from the edge, the cladding will be opposite since the clip represents the hole left from the previous gang punch. There is no specific coin orientation for this anomaly since the orientation of the blanks, as they are fed into the press, is not controlled meaning, the top of the blank may not be the Obverse of the coin. The OP's images clearly show a full copper core which means that the missing area of the coin was ground off as indicated by the horizontal scrapes inside the clipped area. Exceptions to the above diagnostic would be with the straight clip and the elliptical clip. The straight clip could show a thin strip of cladding on the top and the bottom of the straight clipped area depending upon how the strip was manufactured and where on the strip the blank was punched. (i.e. top or leading edge of the strip or from the side of the strip) This would be because no gang punching was involved and the cladding is undisturbed from its original manufacture. The elliptical clip (convex) would also not reflect this diagnostic since the elliptical clip is NOT the result of the gang punching operation. A more detailed explanation was in a Coin World Collectors Clearinghouse article of June 29, 2005 page 50. PM Me and I'll share a scan of the page which was authored by Mike Diamond.
I quote myself to make a new statement... I don't think you have a Quadruple Clipped Planchet after reading the evidence presented by the previous members. I agree with what they have stated. I also say PMD.
Agreed PMD . . . unless a finned rim or rim burr at the outer edge of the rim, the sheared edge inbound of the rim of the coin should not be thicker than the coin itself, which it definitely appears to be. In addition to other comments made, the rims look totally wrong for a coin being struck after clipping the planchet . . . I see no tapering of the rim at all. Speaking of quad clips, I know I have a quad clipped Ike in the SDB . . . I haven't looked at it in about 20 years. Quad clips can occur from advancing and retracting the strip to multiple different positions in the punch press before punching out the subject blank (Press operators call this "jogging"). This would be highly unusual, and likely accounts for the dearth of such examples. I believe it a remote possibility, but possible nonetheless, that a coin may be clipped as many as 6 times. I would pay seemingly insane money for an authenticated 6 clip coin.
Just looking for the first time. The third image shows a coin that has been machined with an abrasive wheel. DING DING DING DING. Alarms should sound and like a construction site without a permit ......all work should halt. Just what my two minutes of time saw. And also just my opinion.
After reading everyone's input, I agree that my coin is not a Quad Clip. As 19Lyds pointed out, the scrapes (or striations) are in the horizontal plane of the coin instead of in the vertical plane indicating a grinding in that direction, not a punching out in the vertical direction. I've included successive pictures of the 4 areas taken outside in bright sunlight for better detail. They all look to be of the same pattern. Also as Michael K points out, with the 4 being at specific points (and approximately the same size), it does seem man-made and not a random pattern like you might expect from clipping. Thought I had a good one with this coin, and so am a bit disappointed. But I do appreciate everyone's input on this coin and I have learned a lot by it, thanks.
I really like posters that actually listen to reason without preconceived notions about what they may or may not possess! Thank You!
