Hi All Another coin from my grandfather's selection of "oddball" coins. As you can see, there was a big scrape out of the coin from the center to the edge. I think this must have been due to a faulty planchet. The edge of the Queen's head, the GR in gratia and the DEI are all formed and raised somewhat even though they are within the scrape. This suggests to me that the scrape must have been on the planchet before the strike and that the lower relief and sharpness of these features is due to the scraped area being at a lower elevation than the normal surface of the planchet. I think if the scrape had occurred after minting, the edge of the Queen's head, the GR and the DEI would have been removed completely. Please let me know what you think! Thanks GRcoins      |

Nice coin!
It would even be sweeter if you had the missing piece.
Oh by the way...Welcome to the Forum!

Yes..  , to CCF Don't know much about errors but, this looks like a major 'planchet flaw' to me..  |

It could have been gouged some time after minting.
What makes me think this is the opposing damage on the reverse side, that resisted the damaging blow by some chisel like tool on the obverse side.

I think you're right GRcoins. This error is caused by a faulty planchet. It is a nice example of a Lamination error. There was a flaw in the blank that broke off when the coin was struck. Sometimes impurities accidentally get rolled into the metal (e.g., slag, dirt, etc) and end up causing problems.
The laminated piece must have detached after the coin was struck because the reverse side of the coin received a full strike. So the planchet was whole & unbroken when it went into the coining press. If the piece had broken off before the coin was struck, the other side of the coin where the flaw is would look weakly struck.

Thanks for your comments!
But would the lettering and the the edge of the Queen's head still be present and somewhat raised in the scraped area if that piece was removed in one way or another after minting? That is the mystery for me!
Thanks for your help!

Seeing ghosting of the Queen's head and the lettering is normal for a lamination error. It demonstrates that when a coin is struck the design gets transmitted right through the whole structure of the coin to some extent. It is pretty cool!
I imagine that effect does not happen for coins that are cast instead of minted in a coining press.

GRcoins...Welcome Take a look..Both marks are about the same length...That could mean a "chisel" was responsible for the removing of metal.   Also look where the arrows are pointing, possible chisel marks..IMO

wert, take a look again at the area. It has "lines", which is characteristic of a lamination. If it's some sort of PMD that large, I'm pretty sure it would show as a deformation of the coin. |

wert, I like your healthy dose of skepticism. I still think it is lamination error though. I have seen similar straight splits on coins that still had an attached lamination.

I would say a planchet issue for sure, if it were chisled off or cut in some way the detail of the hair and letters seen in the void would not be detailed as they are, jmo

Looks like a brittle planchet to me and a nice coin to own!

I'm also going to vote for a flawed planchet. I have a couple from this era that look similar except for the portion that extends beyond the normal circumference of the coin.

The only reason I had thought it was caused by a chisel (and I have done tons of chisel jobs) is that if you look at the YELLOW arrows that roll over is a by product with chisel jobs and the GREEN arrows looks like where the chisel entered the coin... Hey, but what do I know..Too many people here think it is a planchet error, so I guess it is...   |
