Niewmismatic Error Coins

Malaysia 20 Cents Key Date 1969 With Straight Clip Errors.
Rarity:RRR/UNC
In 1969, the 20 cents of Malaysia Parliament House series were minted with a total mintage of 15,000,000 pieces. It was the third lowest total  mintage in 20 cents under Malaysia Parliament House series. The lowest in mintage is 1970 (1,054,000 pieces) minted by Hamburg Mint in Germany, followed by second lowest in mintage, i.e.1978 (6,847,062 pieces).

In my experience, it has been always a tough task to find a piece of uncirculated 1969 20 Cents in good uncirculated condition. And again to own another piece of this rare date 1969, 20 Cents coin in choice uncirculated condition with error is an other big achievement in my error coins collection.

The 1969 20 cents under Malaysia Parliament House series shown on this page is a good illustration of the clipped planchet error showing a straight clip. Occasionally a blank will be punched from an area overlapping the end or edge of the metal strip and the coin which emerges from this mishap will show a straight clip.Clips are normally curved because the blank was punched from an area overlapping the hole left by a previous punching.
A straight clip is thought to result when a blanking die (punch) slices through the leading or trailing end of the coin metal strip. This pre-supposes that the ends were trimmed prior to the coil being fed into the blanking press. Another possibility is the blanking die slicing through one side of a strip that is too narrow. This situation might arise if the splitter, which divides the original wide strip into narrower slips, is not positioned right in the middle of the coil. A small percentage of straight clips mark the termination of a planchet taper. This may be where the rollers squeezed the leading or trailing end of the strip down to an abnormally thin guage. The edge texture of a straight clip is highly variable. It can be smooth, rough, irregular, or serrated in some fashion.

The below sequence of images illustrate metal flow and the taper and fadeout of the design rim. This is what we would expect to see when dealing with authentic straight clips.
The illustration below shows the overlapping punches on the coin metal strip and what hypothetically could happen if the punches (red arrows) went over the leading or back edge of the metal strip; if the strip was not cut straight; if the strip was too narrow; or if the strip was somehow fed into the blanking press at an angle. All would result in some configuration of a straight clip as shown in green
