Just purchased on ebay. Seller says the coin is non-magnetic and weighs 3.24 grams.
Do you think this is a 2010 20p struck on a 5p planchet?
Has anyone seen other examples?
ChatGPT deepresearch found several examples in other years, but only one possible example of a 2010 on checkyourchange.com.
It was listed as a 20p wrong planchet error, but that listing said further details were needed, and no specifics on which planchet were given.

Ref number 20P028
Coin is in transit from UK, so I only have images from ebay ad. |

I am sorry for the naïveté if this is a simple one.
Can I please get some help on what causes the raised columnar marks on the top reverse of this off center cent?
It can't be a die issue (die break or a strike-through that damaged the die), because it is present in the non-struck off-center section.
Similarly, it seems like it might not be a retained struck-through because it appears to be embedded into the nonstruck section and that doesn't make sense. Also, there's no pattern struck into it on the minted portion, and it appears to be the same metal as the coin, which also seems to suggest it is not a retained struck-through.
Perhaps it is a planchet error, or is it something else entirely, like PMD?

Good catch! Thanks.
Interesting, the VV stages don't correspond to the progression of the column die breaks. Stage A starts off with moderate dies breaks, they progress in Stage B, this transitions to no column due breaks in Stages C-F, then they start again weakly in G, and slightly stronger in H.
How would that work? When the reverse die was getting worn but still useable, a new obverse die with RPM-002 was switched in. Then the reverse die was switched out and more coins were minted? |

Thank you!
I have a naive question. The die file lines are more extensive than the VAM-1BQ reference image. So much so that the top of the ray is missing. Is that how the VAM naming convention would apply in this case? Where the VAM designation (1BQ) not only refers to the state shown in the reference image, it also refers to later stages that have had additional die corrections? |

Is there a known 1923 VAM with a shortened ray on the reverse? I couldn't find it.
The shortened ray is due to extensive die correction, filing etc. presumably to resolve an issue like a clash. There looked to be some clash remnants, like east of the lower olive branch so I was wondering if I'm missing it because it's a later corrected stage of another VAM that is a known clash and that clash is hard to see?

It was on eBay. It sold today for $306. Gave me a sick feeling when it blew past my bid.
Anyone have a guess what it's worth if it's a fissure, blow out, or the like? I did a comprehensive search, and nothing online was as extreme, if that's what it was.
Sorry about the blurry images from the eBay ad. It probably didn't help that I did a background subtraction on the images to preserve as much resolution as possible. I might have caused some edge issues. |

| 181? Large Cent With Both OBV And REV Mirror Images

There's a page on errors-ref.com called
"Brockage-Counterbrockage Combination 8 Types
PART VI. Striking Errors:
Counterbrockages:
Brockage-Counterbrockage Combination (8 types):"
They explain how a mirror image in relief occurs. It's just a clashed die cap, which takes 2 different events and is rare. Die cap, die clash on capped die, early strike on coin minted with clashed cap and opposite die with clash from cap.
They also give examples of very rare complex multi-step bockage errors.
I just can't get my head around the steps required to mint a coin that has both sides in both mirror image and relief even with this information.

Thank you for the suggestion. It is the obvious answer and helpful to see the PCGS damage designation.
I just can't figure out how a hammer job creates patterns in relief. I don't know if you can see it well enough on the reduced size image files. On the original large sized files it looks like both sides are in relief, not incuse.
I'll post an update if the seller messages me back about it. |

I can't get my head around the multiple events required to produce this error.
Any guesses on what sequence of capped dies, clashed capped dies, or flip-overs would be required?
Of note
I just asked the seller if the mirror images are incuse or relief. They look like they are in relief to me from the images, which makes things even more improbable.
Also, coins were minted by hand at this time, so it's less likely events could stack up as easily.
It's been graded, and deemed authentic, but no error designation was given.
