Niewmismatic Error Coins

Malaysia Parliament House Series 1981 10 Cents And 20 Cents With Double Strike Errors.
Rarity:RRR
The Double Struck coin results from a simple malfunctioning of the ejector system of a coin press, in consequence of which the coin is left in the collar to receive a second strike. If the position of the planchet is not disturb, the second strike is imposed directly upon the first, and is not detecable. Should the planchet rotate between strikes, it receives two separate and distinct impressions. As with off-center errors,the value of a double struck coin is directly related to the degree of the variation.
Double Struck occured at the position of 2 to 3 o'clock obverse.It is a 95% Off-Center Struck errors when it received a second strike.
