1963D Nickel w 5% clipped planchet. Does the clip occur before the devices or after? Would a clip create a doubling effect? Or could a clip happen on a doubled die? I think I see a split serrif on the right bottom leg of the R. I'm not sure if its Machine Doubling on the M in America? Any thoughts would be appreciated.

A Clip actually happens to the planchet, before the coin is struck. It happens when the planchet punching machine (the machine that punches out the circular metal material called "planchets".) overlaps an already punched out hole, causing the machine to accidentally punch out a portion of the already punched out hole (which is the clip you see on your coin). And yes, a Clipped Planchet can also be struck with a Doubled Die, (A Doubled Die. It happened in the die creation process, so the die actually the doubling on it, hence the term "Doubled Die". The doubling is actually on the die itself.) Not seeing a Doubled Die on the obverse. And finally, I only see Machine Doubling, on the reverse.

Clips happen before the strike. They are an issue with metal feed into the machine. If something is not started correctly, they it is started again.

Normal coin web:

Some of the straight clips are from the metal not being feed horizontally with the feed and the metal is not over the cutters:

These are punched out to form blanks:

The blanks for feed into the upset process to add the proto rim:



This turns them into planchets:

After the upset process, and they are now planchets, they are plated.

But if a blank/planchet is missing an area, the setup will show that the rim was not setup correctly. When the coin is struck the area 180 degrees from the clipped area will show weakness because of the missing metal on the blank, doesn't raise that area. So on a incomplete planchet, the area to look for will who 180 degree opposite the curved/straight clip/clips. This is called the Blakesley affect. (Noticed by a weakness of the rim:



Note how the affected area widens because of the setup area is not strong enought:



Triple Clipped coin:

Note the Blakesley areas?

When there is a hug clipped area, then the Blakesley affect will be less noticeable:



Note the center edge is distorted from the strike?



Note how the arc of the clipped area is slightly distorted?



Out of collar clip:



Fake Zincoln clip. How to tell?

Looks for the unplated edge of the clip. Someone cut the coin.
Hope this helps a bit?

Coop, that 1973 D Jefferson nickel Straight Clipped Planchet is also showing severe Die Deterioration on both the obverse and reverse die. Very heavy die flow lines and severe breakdown of the die is visible on both of them. Man, that die was so shot! It was definitely at its end of its useful life and should have been retired a long time ago. Just something I wanted to add to this thread, for education purposes.

Thank you both!! Such great information from you guys! I know I ask a ton of questions but I really want to understand. From the bit I have learned, if you see a split seriff you most likely have a doubled die? Is this correct? Maybe it only applies to RPMs? I don't know.
If this R isn't a split seriff, what is it?

Rabbithole1, yes, a notch is sometimes an indicator of a Doubled Die, but not always though. On the letter "R", that looks like a well placed hit that caused the metal to be pushed over and flattened, on the area.

Coop,

I read your post with interest and pulled out my coins to check them against your photos. One of them seems to match a minor double die you have depicted; my 1962 Philadelphia proof nickel. I attached a picture to ask if you see it too. This is the best I could do through the mint set wrapper that still protects the '62 proof set. If you have time to look, what do you think? Does it look like it to you as well? Thanks in advance. Also thank you for the terrific information!

C.S.

Your looking on the right areas, but this is not showing enough spread to be listed. The horizon devices are the correct area, but just not enough spread. Now with that information, you are on your way to find more doubled dies on nickels.
