Skeptical. The denticles right next to the clip look too well formed. I don't see any tapering of the rim into the clip either. A pic of the reverse and an edge on view of the clip might help.
Yeah...I have the same impression. Since the clip is an empty area when the coin is struck, metal should be flowing into this gap, and therefore there would be less pressure to strike up the denticles around the clip. But, there is there no difference I see in the denticles--and there should be for a real clip.
It doesn't have anything to do with weakness in the denticles adjacent to the clip. The weakness should be evident opposite the clip. http://dniewcollectors.blogspot.com/2012/04/blakesley-effect-on-clip-error-coins.html Chris
Chris, I wasn't discussing the "Blakesley Effect" in my post. It's a fact that when planchet metal flows into the recesses of the clip when struck, there is less metal to strike up the denticles adjacent to the clip--as the picture below so clearly illustrates--different coin, but same process.
Here's mine, can see the weak denticles and the Blakesley Effect, plus it is curved. Bought this at a flea market for $0.25 because the seller thought someone took a cutter to it.
Well, we'll just have to agree to disagree. Please explain where these recesses are. By any chance are you confusing the recesses from a cud where the metal flows into the break causing a weakness on the opposite side of the coin? If you look at the link I provided, you will see that the coin is well struck adjacent to the clip. Chris Kentucky, the arc on your clip doesn't look like the perimeter of a cent. It looks too shallow, almost like a half dollar. Maybe my vision just ain't what it used to be, but could you take a photo with another cent in the arc? Chris
I think what I'm describing is pretty clear and logical. When a clipped planchet enters the coining chamber, the "recess" I'm talking about is where metal is missing--due to the clip. When struck, pressure is exerted from both sides onto the planchet. This causes metal to flow into that "recess" (the clip). Because metal is flowing into the gap, there is less pressure to strike up details such as denticles right next to the clip. This isn't my own idea, but something I've learned from error experts like Mike Diamond. I think both pictures above of clips on IHCs shows this clearly--as well as that "Blakelesly Effect" too.
Photo was one I took some time ago and posted before on CoinTalk and everyone agreed it was a "good" clip. I'll see if I can find it, or try and superimpose another copy of the same cent on this one.
Yeah...you have to remember, that arc can change its radius due to metal flow when struck in the press. The arc tends to flatten out due to metal flow from the center outward.
I get you now. The use of the word "recess" had me confused because it isn't really a recess. It's the missing part of the planchet. Chris
Right! You'll have to excuse my lack of comprehension regarding your first explanation. The word "recess" got me and this now makes more sense. Chris
