My constant look out for weird coins landed this monster into my palm. I am still now still in disbelief that I have acquired the mother of the doubled die coins of Malaysia.

The first time I know that this DDR exists is when I stumbled upon an article from NUMISMASTER.COM.

It is quite amazing and proud to see a Malaysian variety coin appeared in a well-known US coin collector website. It is found out that the first known of this DDR now reside in Hawaii, far away from her motherland. She flied to Hawaii across the Pacific Ocean! To such extent the elusiveness of this coin can be said.

In my attempt to recognize the type of this doubled die, I think this is a Type V - Pivoted Hub Doubling Doubled Die.


This type of doubling occurs due to working hub is not properly aligned with the working die. This type of doubling is quite similar with Class 1 (Rotated Hub Doubling), but the pivot point is located somewhere around the rim. Thus, doubling magnitude is not the same along the rim.

The doubling is strongest on one side (in this case, left side of reverse), with little or no doubling on the opposite side of the coin (right side of reverse, see 7 of 07 and A of MALAYSIA). The doubling will increase as you travel around the rim of the coin until you come to the widest doubling. From this point on, the doubling starts to decrease until you return to the starting point with no doubling. This point of no doubling is called pivot point. The pivot point of this coin is found at 3.30 o'clock at the reverse.

And the doubling is in counter clockwise direction.

These two photos are for you to enjoy! Sorry for the low quality photos as I used a scanner, need a proper camera to capture her beauty!
