Rarity: RRR
One of the interesting minting varieties that escapes most collectors is the Rotated Die Error—yet it is the easiest to spot if you remember to look for it.
There are three basic causes:
A loose set screw that allows the die to turn in the holder;
A broken die shank that allows the die face to turn; and
A misalignment due to the die being installed improperly.
The loose screw is blamed for most of the early rotations, with the other two causes dividing up a minority of the rotations.
Rotated Die Error coin is produced during minting when the dies for the reverse and obverse of the coin are not aligned correctly. This may be because it was incorrectly installed in the press or it rotated during the production run of coins.
For Malaysian coins if you hold the reverse of the coin upright with a thumb and forefinger on the top and bottom edge you should be able to rotate the coin around to view the obverse which will be upright also. Malaysian coins are minted in what is known as ‘medal alignment’ -the back and front or heads and tails are both upright when viewed.
Coins from other countries such as the USA for example mint their coins in what is known as ‘coin alignment’. This means if you hold the reverse of a ‘coin alignment coin’ (such an an American quarter) upright and rotate the coin around to view the obverse it will be upside down (in contrast to Malaysian coins).
A regular coin should have the Parliament House, the crescent moon and the 13 pointers star on the obverse position at a right position. During minting one of the dies might not be aligned correctly or might rotate during the production run. When turning the coin around, if a coin is an upset it will show the reverse (denomination’s side) will be upside down . She may be leaning over to the clockwise (CW) right 90 degrees (a CW90 degrees upset) or upside down/ inverted (CW180 degree upset). You may find these upset errors in any number of degrees of the clockface.
If one side of the coin is only rotated a small amount, up to say 15 degree (or 1 o’clock position) it won’t be considered a rotated die error coin. This angle may be considered normal as there is a small allowance (tolerance) for slight angle movement in the struck coin.
A Rotated Die Error coin will demand a premium over it’s regular counterpart. The degree of upset will also determine how collectable it is. A Malaysia Parliament House series 50 sen coin upset with a 90 degree angle may fetch RM150 or more depending on it’s condition so it’s worth looking out for this error in your change.
A Rotated Die Error Coin with a high degrees of rotation will certainly command a higher premium as they are much less common.
