A favorite type of clip! Never get tired of seeing these in their myriad of designs. Congrats!

Part of the Blakesley affect of the cracked planchet. Without the resistance of the metal on the upsetup process, their is weakness on the rim on that area. (lack of the full proto rim on that area) ))_HAcoins_AAA.jpg) |

Nice ragged clip. Congrats.
Words of encouragement are one of the major food groups.
We need to consume them regularly to thrive and grow.

I wouldn't call it a clip exactly, possibly an impaired planchet or even blank.
Very nice indeed. I think is a nice find.

This it is planchet default. Is very clear, and we can see that the placket was divided before all other procedures. Show so nice the bronze structural separation during the rolling. I like this coin.

Very nice error! I've been looking for one like this! This one sold on Heritage recently. I wanted to bid on it, but it went way out of my range. It sold for $660.

Wow Yokozuna, that is a neat looking coin although I think that is more of a ragged perforation ( Blow Hole) error rather than a ragged clip.

I think that was what Yoko was trying to say. Your coin is not a ragged clip, but rather a blank deformation. Not fully filled in when the copper sheet was rolled out. Indeed it was possibly near edge but not at the edge. (IMHO)

Indeed it was possibly near edge but not at the edge. (IMHO) Dearborn, take a look at error-ref of Ragged Clips. https://www.error-ref.com/?s=ragged+clipThe term ragged clip refers to blank defect and while this could be more of a ragged notch or ragged fissure they are closely related as per error-ref definition. "Ragged clips can also be derived from the middle of the strip. As the strip is rolled out, ragged fissures sometimes develop. If a blanking die slices through such a fissure, the resulting blank will have a ragged clip indistinguishable from one derived from the ends of the strip."

To answer to all: "Ragged Clips" is what errors site named those rolling errors, I say errors because metallurgical are considered errors. Quote:
Edge cracks occur if rolls have excess convexity. They occur when the center of the metal sheet has more elongation than the edges. This leads to a defect called center buckle. Edge defects are due to heavy reduction. Small thickness sheets are more sensitive to roll gap leading to greater defects. Thin strips are more likely to undergo waviness or buckling.
During rolling, the metal sheet has a tendency to deform in lateral direction. Friction is high at the center. Therefore, spread is the least at the center. This leads to rounding of ends of the sheet. The edges of the sheet are subjected to tensile deformation. This leads to edge cracks. If the center of the sheet is severely restrained and subjected to excess tensile stress, center split can happen. Non-homogeneous material deformation across the thickness leads to high secondary tensile stress along edge. This leads to edge cracks. Secondary tensile stresses are due to bulging of free surface.
Due to non-homogeneous flow of material across the thickness of the metal sheet, another defect called ALLEGATORING occurs. This is due to the fact that the surface is subjected to tensile deformation and center to compressive deformation. This is because greater spread of material occurs at the center. This it is the really explanation of this ALLEGATORING error on the rolling and planchet: non-homogeneous flow of materialthanks for attention PS: There are four main metallurgical processes for the manufacture of finished metallic products where the metal products can pick up defects. The defects picked up during these processes are 1. casting defects,
2. rolling defects,
3. forging defects,
4. welding defects.Edited by silviosi

Tomato, tomoto, what difference does it make. Error ref says ragged clip. That's what I've called it for 50 years.

@Cujohn: you say "tomato". I explained what is in fact the Rigged Coins as per Error.com, where they use this term for all the subdivisions of the Allegatoring errors. If you do not want to understand how was occur please keep your remarks for yourself. In the definition the Ragged term is: "having an irregular or uneven surface, edge, or outline".
Sorry to tell you but if from 50 years you do not understand the term and the physical effect on the coins, then all this time you was in potato's.
