Found this one some years ago in a mint sewn bag. The planchet split before it was stuck. Possibly before it went through , or as it went through the upsetting mill because it does still have a bit of a rim on the obverse split side. The coin weighs 1.6 g. so basically it split in half.

Very interesting. If you didn't say it was found in a bag, I would have assumed PMD. |

Couldn't have been PMD. Too much evidnece against it. Really nice half find. I wonder if the other half made it out.  We may never know. Very awesome error.  It is hard to tell if it split pre or post upsetting. |

This is a really nice one! I have a decent one of these laying on my desk somewhere that I'll have to shoot one day. I sort of collect these as I always buy them when the price is reasonable. I think I have about 20 of them so far.

I wonder how many of the blanks were loosen/split because of the upset mill? That would be a reason they occur. But most often they split off after the strike. Looking again at the images for this coin, I'm thinking it split off after the strike. On the split off before the strike examples the devices maybe weak, but some are formed.   Note how the devices on scotty11's are formed, but weak. (because of the missing metal on planchet) On Stoneman227's images they look like it split off after the strike leaving many of the devices rough? So I'm thinking his coin split off after the strike.

Coop , just wondering the weight of the coin you showed. If there was more metal left for the dies to work with them the bust would have filled in to a greater extent. Also note the metal striation line extending into the field from the rim in front of lincolns face. It is a obvious lamination remnant but the field of the coin flows smothly up to it . In my opinion this spot could not have flaked up after the strike. I have alsonever seen a lam that only affects the high , last to fill areas of a coin.
There is also a similar lack of fill on the reverse that coresponds to the laminated areas on the obverse. The metal was not there to fill these areas of detail before the strike.

Thanks for the link Coop !
Thinking of Progressive Indirect Design Transfers. Quite common on wheat back cents and not often seen on memorial back cents. The reason is, there is a minimum of central design on a wheat back so the impact of the dies has a better chance of passing through the coin metal and impacting the other die. The memorial on the reverse , because of a larger central design ,allows a greater flow of coin metal in the center thus cushioning the blow of the dies.
My coin has two things that create the difference needed from the illistrated coin. Mine is a memorial, thus needing to consume more coin metal centrally to fill the designs and it is 4g. lighter. This is ultimately supported by the lack of design fill on the reverse mirroring Lincolns obverse bust.

Well it maybe be a split before striking the planchet. Thanks for the update.
