Here are just a few photos of this really nice double clip on a 1974 Nickel. Mint mark would have been clipped, though there is a small raised dot on the edge where it should have been. Perhaps it is a Denver minted coin. First image shows the actual amount of rotation, the following images are rotated normally for ease of viewing.    Get your guesses in for the grade, because its about to get slabbed  |

Most impresssive, but way over my pay grade.

With that much missing I would expect a softening of the devises next to the clips. Good luck with the slabbing.

very impressive double clip, but I think that the rotation is normal. By looking at the bottom 2 images, you have the obverse with the space between the clips threctly at the bottom, but that has Jeff leaning forward more than it should be. with the reverse you have the space rotated CCW to get the memorial level.
To get Jefferson to appear as to not be stooping over, you need to rotate the nickel CW to get it correct.
I have the exact same issue with non clipped nickels when placing them into my albums, I think I have Jeff upright then look at the reverse and the reverse is showing rotated. So I had to start installing my nickels in my album by the back side of the album page to get the memorial correctly oriented. Then going back to the front of the page, you can see Jeff situated as he should be.
The main problem is, is that there are no indicators when you are holding the nickel upright and level.
At first I was thinking that all my nickels had an orientation issue.

Yeah I wasn't trying to mislead anyone, I was trying to imply rotation is exact as in from the obverse placement to the reverse they line up correctly. With this nickel in particular, my OCD eats me alive when they are placed in the "proper" orientation. Here is what I had originally done, vs the proper orientation.   |

Rim looks a little weak by LIBERTY, which seems like a good thing. Please follow up with this thread when you get this coin back from the TPG. I'm interested to see where they grade it. Thx. "If you climb a good tree, you get a push."

Don't see any evidence of Blakesley effect.

While I was marking up pics, you explained to Dearborn already.... I'm too slow.  I have a bigger issue with the coin not being oriented correctly, than the clip not. I know very little about clips but hope you knock down a great grade!   -makecents-

In your new images, I believe that the second one correctly show the correct orientation from obverse to reverse. I definitely under your OCD when it comes to everything being perfect. I'm in that same OCD boat with you (I have the other oar- paddling right alongside you-LOL) Quote:
Don't see any evidence of Blakesley effect. I do, on the rim opposite each one. Albeit weak, but it is there. |

I actually laughed when you originally posted about the orientation because before I made my post I had a brief internal debate whether or not to post it correctly or not. Quote:
Don't see any evidence of Blakesley effect. The left clip (from the obverse side) has the very weak "ERICA" in America on the reverse + slight softening of the rim around "LIB" in Liberty on the obverse. The right clip (from the obverse side) has the beginning signs of a flattening rim above "RUST" in trust. The coin is within a few arc seconds of being absolute parallel to the camera sensor. So whatever rim variation is true to the coin. Quote:Please follow up with this thread when you get this coin back from the TPG. I'm interested to see where they grade it I'd be ecstatic with a MS63. Then I see photos of 1980-D nickels on PCGS and rethink everything I know about how to grade a Jefferson. |

Me I look more of the clip borders. What look the sides of the clip? And also why is rim on the tinny part?!!! I magnify the photos and do not fit my narrative of the double clip. A new man made error?

To fit my so called "narrative" here: Taken via an Olympus SZX12 at roughly 75x total optical magnification. Equivalent to using a 7.5x objective on a normal microscope.   Last image is at over 100x total optical magnification. Or roughly a 10x objective on a regular microscope.  Per the Error-Ref page: Blanking And Cutting Errors
Part V: Planchet Errors:Blanking and Cutting Errors: Quote:
3. "Cut-and-tear texture" on the exposed edge of the clip. Only curved clips and elliptical clips will have this feature. It is also referred to as a "breakaway zone" or a "belly line". The cut-and-tear texture refers to the microscopic texture of the clipped edge. Part of it is smooth, while part of it is grainy. The grainy part tells you that this was the original bottom of the coin metal strip. As the blanking die (punch) penetrates the coin metal strip, it forces a blank through a hole in a perforated base plate. The sharp, right-angle edge of the blanking die slices through the upper part of the coin metal strip. The lower part of the blank simply tears away from its hole in the coin metal strip as it is pushed down by the flat face of the blanking die. Quote:
and just what instrument did you use to measure this? A pair of stacked precision goniometer cradles from Newport. I do a lot of stuff with laser optics, so no, not many will have something like that. |
