MALAYSIA COIN STRIKING ERRORS:FINNED RIM ERROR PROOF COIN
Malaysia Finned Rim Error Proof Coin.
Rarity:RRR(Proof)
The proper term for this type of raised-extra-metal-around-the-rim error is a Finned Rim Error Coin. The cause of this error is usually one of this two things. Either the planchet is too heavy for the normal die spacing, or the dies are improperly spaced and coming too close together during the strike. This causes excess metal to squeeze up between the dies, resulting in the extra bit of raised metal around the rim.It would seem likely that the latter problem is what accounts for the finned rim error here.
Earlier,this Proof coin was mistakenly called the Misaligned die (MAD) struck error coin.MAD is occurs when the top and bottom dies are not in alignment with each other. The results are one side of the coin design is offset while the reverse appears normal.
Obverse is the effigy of Malaysia Agong, KDYMM SPB SULTAN HAJI AHMAD SHAH AL-MUSTA'IN BILLAH.

Finned Rim Errors occurred around the rim.It exhibited sharp-edge raised rim with a 2.00mm of highest raised rim at 12.00 o'clock position.
It is pretty rare to find one on a Proof coin since they're so carefully struck.I am willing to pay RM 380.00 to own one.
Hello Dickson,
ReplyDeleteLooking at your coin, I really don't see any issue of MAD except for the slightly 'finned' wire edge as stated by you. MAD refers to the centeredness of the striking on the planchet and in relation to the opposite side of the coin and the irregularities of the edge is another separate issue altogether.
For the edge, "finned edge error" or "struck with collar too high" can be appropriately used to describe their oddities.
Cheers!
