I have stumbled across this 2001 5 cent coin which has a ring around the outer ridges of the coin making it look like it has a square pattern. Question: Is this something which is special or unique? Should I keep this coin due to it being worth something? What would this be this called? Thank you in advance  *** Edited by Staff to Add Year / Mintmark / Denomination to Title.

Looks like someone was going to try to make a Magician's coin but decided it would be too difficult and put it back into circulation. No error I'm aware of would look like that straight from the mint, so I'd be fairly confident in saying PMD. However, that's just my opinion, so hang onto it just in case someone else can come up with another answer. life is a mystery to be lived not a problem to be solved

what is the weight of the coin, that would be a good starting point.

the weight is the same as compared to other 5 cent coins @silverwolf. Additionally it does not seem to be a Magicians coin @Nevol |

This sort of thing is quite common on pennies and halfpennies. In my opinion it has something to do with the collar die. Exactly what I don't know.Like most of these things there is little info and lots of theories.  |

Close up of groove with a USB Microscope may be able to show if it has been cut( PMD) in or not. I have had a 1937 and 1938 Crowns with a similar groove cut in by a jewelers lathe. It was done to set the Coin in Silver/Gold mounts but the groove was slightly deeper than yours in/on a much bigger Coin. |

I would say no, it's PMD but yes I would keep it due to it's uniqueness, but not for it's perceived worth. I can't see how this type of error could occur during the minting process, unless the sheet that these blanks were cut from had this fault, but if this was the case then you would expect that more with the same fault would have been found? |

Hi I have seen a few coins with the same line or damage/error sold recently pn ebay. For what it is worth they have all been 5 cent pieces and from 2001 also. Dont know if that helps but they have been selling for around $30-$40. Dont know if that makes them legit or PMD? |

Good pick up Auscoin, a quick look on ebay confirms that there are at least three 2001 5c coins with the same error up for sale at the moment. Edit - tried showing the links to ebay but had no success ... try typing in 'Australian 5c 2001 Error Coin' to see.Edited by coaster

What we really need is an Aussie who knows exactly how the minting process is done in Australia. . Couldn't agree more, but I believe Mint employees have to sign a confidentiality agreement, so not much info is known. I have in the past had a close look at the milling on a lot of coins and I believe there is a whole new world of varieties in the shape of the teeth, missing teeth,part missing teeth, but put it on the backburner as many would say it is just damage. Also I had a quick look at my stash of the 2001 5 cent and have found similar grooving, mostly slight but it is there.2001 seems to have been a bad year for the Mint!!, with faults on most denominations. A lot is spoken about faulty obverse and reverse dies but little info about collar die faults or damage. There is still a lot to learn in my opinion. |
