Good morning .... After your learned opinions for this one .... thanks  I've looked and relooked to see if it's PMD or not. I don't think it is but I would really appreciate some other eyes. (Mine are not that great). Note the curved impression between the denticles and text above the queen.    Edited by The Unicorn

It looks like a Lamination Issue, like a planchet flaw or a mixture of the metals. Or some one took a chisel to it it

My eyes are pretty RS as well But I can see this is certainly PMDIt has taken a hit with something sharp.  It's shame this looks to be a nice coin otherwise |

Thanks Trout and CG, I appreciate your input. I thought similar. I wish I had a picture of it from years ago it used to have a 'flap' section similar to the large piece near the chin, except it was over the deepest hole section and was closed along the base of the II. Hence there was the indentation and a 'flap' on each side. (Almost bomb bay doors looking). Unfortunately it must have fallen off.  |

I reckon it might be a lamination error. Could just as easily be PMD. Its a close call. Going from the photos and if I had to pick I would say it is a lamination error and not PMD. |

Quote:I reckon it might be a lamination error. Could just as easily be PMD. Its a close call. Going from the photos and if I had to pick I would say it is a lamination error and not PMD How can you say that ? It clearly looks like a screwdriver ( probably one of them small precision types) with a very fine and sharp edge has been forced through the surface of this coin. The damage is too square and even to be anything else. There are even little rib lines where the screwdriver has been tapped to remove a sliver of the coin  On all the lamination's I have seen the underlying metal is uneven and nothing like this at all. |

Hmmmm ..... you've all got me thinking again. Originally I had a lovely (wish / dream / delusion) that it was a minting error. But it looked so much like a possible PMD. The lack of any damage on the reverse made me hope it was not PMD. (Hence the discussion). Anyhow, Enworb's got me thinking again. So I've snapped a couple more pics and the following is my 'minting error dream'. The previous coin did not eject properly from the die and when the new planchet was loaded it was standing on it's edge on top of the new coin. The strike belted the edge of the coin into this one, possibly curling both sides of the rim into this planchet. The pressure flung the previous coin out of the die, leaving the exit marks seen in the pics. The coin was then minted. A shortage of metal causing the poor stike on .II. OK, so that's the dream, a sixpence fits perfect in the main centre void and the lines therein almost look like milling. Hmmm .... theory pics follow with discussion ....  Below is the above pic marking Milling and exit lines and weak strike .II.  Similar to above, but shows some detail clearer  The pic below shows the possible exit mark leaving under the H etc.  I'll try to get some better / clearer pics. PS: Hey Trout .... I hoped this forum thread helped liven up the discussion!! |

It has most certainly made me take my tin foil hat off  Nice theory but wouldn't the milling on the offending coin leave grooves 90 degrees to where these grooves are It's easy, simply change hats and have another good look   |

"How can you say that?" Are we not allowed to have differing opinions? I would be happy to have this in my collection described as a lamination error. The bit that makes me think that this is a lamination is the extension of the 'flap' outside the suggested PMD zone.  |

Absolutely a forum is a total waste of space without differing opinions  I will wander off to my shed/error mint and try and emulate this error for you. The crack you outlined looks like a stress fracture due to the force involved by the PMD event. I will post pics tomorrow |

Just my opinion, I think it's more likely to be a lamination fault. life is a mystery to be lived not a problem to be solved

Enwarb the 2 coins you posted have NO relevance to unicorns coin. there is NO design to impart on where the damage is done the sixpence. None of the metal has been removed from either of your coins and I would bet that they weigh what they should. IF the sixpence is an error it would be called a lamination peel because the damage is incused into the coin. Your coins however look like something has damaged the planchet before the coin was pressed because the design is where it should be and no metal has been lost from the coin. The thing that really makes me think this is PMD is the colour of the metal. It is brighter where the "flaw" is and this is not consistent with a peel. Normally a peel occurs because the metal was not mixed correctly or there is a contamination in the sheet before it is punched and this would show up in silver as a darkening where the metal sheers from the coin. Just my opinion and how I came about it |

Good to see so many, up so late, for sixpence! (No I really do appreciate it). (Trout .... good luck in the shed  ) |
