image 1: obverse and reverse of the coin

    This is a 5 Sen coin, dated 2006 which has a curved clipped planchet error about 2% located at 9.30 o'clock on obverse.

    This error happens when a coin was struck on an incomplete planchet. It is possible to have curve-shape clip, straight clip, and ragged clip. Several numbers of clip can take place on one planchet. Size of the clipped area and number of clip are the main factors of how interesting the error coin is.

    There are several ways to identify whether the clipped planchet is an original due to missfed blanking machine or a post mint damage due to cutting.

1.  Examine the area opposite directly to the clipped area - An original clipped error will cause this area to have weaknesses, especially at rim's area. This effect is called Blakesley's Effect. Refer to image 2

3. Examine the detail near the clipped area - Especially at rim's area, those area near the clipped area will have the fade away effect.Basically the rim will taper off into the clip. On a fake clipped coin, the detail will just come to a sudden end. Refer to image 4.

4. Examine the clipped end - A genuine one never show a raised edge of metal, which indicates shearing and the details bordering the missing metal should not be crispy. On a thicker coin, sometimes the clipped end appeared to be like have been bitten, producing two-layers-like edge.
