That is not the "Blakesley effect". It has a rim where the purported clip is. If it was a true clip, there would be no rim. It could not have a rim due the to the nature of the upsetting process during the planchet preparation. The "Blakesley Effect" you see is actually "Newton's Law". It's simply a coin that met an object in motion and happened to be between it and another object at rest. The object at rest won, and the coin paid the consequences for it. It's Post Mint Damage.
Below is a true clipped planchet error. As well as the dime above. Notice in the photo below, the absence of a rim at the clip, it's because the diameter of the planchet was not enough to upset the rim. Upsetting the rim is done prior to striking. Upsetting is the raising of the rim by rolling the planchet under tremendous pressure. You'll notice that opposite the clip, there is a weak rim. Same reason, it's because there was not enough pressure at that point to properly upset it. There is no rim at the clip, because there was no metal present to upset. The missing rim at the clip and weak rim opposite of the clip are what entails the "Blakesley Effect". Note the details of the Y in Liberty disappear towards the clip. Also note the texture of the metal towards the edge of the clip. This is because of the strike pressure forcing the metal to flow towards the empty space left by the absence of the metal. The metal was able to free flow and not take on any of the characteristics of the die. Also the shape of the clip is not a perfect crescent again, because of the metal flow. Here is a wonderful article on the clipped or incomplete planchet. http://board.conecaonline.org/showt...d-to-Know-about-the-Incomplete-Planchet-Error
dude, if you cant tell that that is damage, you need to do a lot more research before looking for any more error coins..
@tomfiggy your coin has a rim in the damaged area. An incomplete planchet error coin will not have a rim because the area of the clip is missing so much metal that when it passes through the upsetting mill there's nothing for the wall of the mill to press against to force the edge of the metal into a rim.
It should be pointed out that the Blakesley Effect is not always seen on clips. The size of the coin and the size of the clip can be a determining factor. The dime clip posted earlier is an example. Chris
