Malaysia Parliament Series 1970 Cent Coin 
With Rotated Die Error.

Last Sunday, when I was in Amcorp Mall attending appointments. I happened to collect this rare date 1970 1 sen Malaysia Parliament series copper coin with a Clockwise 45 degree Rotated Die Error.

Being an error coin enthusiast collector since 2007, this is my first encounter with such rare date 1970 sen with an error. And it is a brilliant uncirculated (BU) coin in condition.
Obverse 45 degree clockwise rotated.

What is the Die Rotation on a Coin?
Definition: Die rotation refers to the location of the coin's image when the coin is turned over. For example, if you look at the obverse of our Malaysia Parliament series 1 sen coin with Parliament House right-side up, and then turn the sen over from left to right (or right to left), the denomination 1 should be right side up on the reverse. This is called "coin alignment." Normally, a coins design is upright on both sides when the coin is flipped over. A ROTATED DIES error is when the reverse die is not aligned properly with the obverse die. 

This type of error can be easily identified by holding a coin at the 12-o'clock and 6 o'clock position between your thumb and forefinger, looking at the obverse design upright, and flipping over from side to side, i.e. left to right or right to left. If the design on the reverse isn't upright (looks rotated either clock-wise or counter clock-wise), you've found a rotated-dies error. Some rotated dies can be quite dramatic, some even a perfect 180 degrees! With some searching, they can be found in pocket change.

Rotated die coins usually occur in two different ways, the first being the mint employee installs the die incorrectly so the obverse and reverse do not line up properly when the coin is struck and the second is when the die becomes loose and then moves a little bit as each new coin is struck.

All Malaysia coins, and nearly all world coins, are struck in one or the other of these proper die alignments. Die rotation errors are known to exist, where the coin's reverse isn't precisely lined up with the obverse. Many Malaysia coins have been found with die rotations ranging from a few degrees off, to a full 180 degrees off!
