Niewmismatic Error Coins

Malaysia Parliament House Series 1979 10 Cents Coin With Rim Clip Errors and Blakesley Effect.

Rarity:RR/UNC
This Malaysia Parliament House Series 1979 10 Cents coin is an other good illustration of the Rim Clipped planchet error coin showing a curve rim clip.
Few diagnostics for genuine rim curved clips are:
1. The pole opposite the clip often shows a weak or absent rim. This is the "Blakesley" effect.
    Special Note: The "Blakesley" effect is not always seen on coins with authentic curved clips which are  LARGE.
2. Design elements bordering the clip often show metal flow -- a smearing and stretching out of the design.
3. The exposed edge of the clip will usually show a "belly line" or "breakaway zone". Half of the exposed   edge (upper or lower half) will be grainy and the other half smooth.
4. The rim should fade out and taper toward the clip.
The Blakesley Effect is a term used to describe inefficient metal flow, opposite a clip on a coin ( "opposite a clip on a coin" it means the effect will be more or less CW/CCW180 degrees around the rim) from the clipped area., when the rim is formed and the subsequent imperfect or incomplete rim formed at that position after striking.
