From what I am learning because it is going rim to rim and affecting a device (the 2) it would be considered a Retained Cud. We'll see if I am learning correctly now. |

Its not a die crack. It is something on the coin. Note how it extends over the rim. The last picture can see it over the edge of the coin.

Oh man, I thought I had it. Still so many details to learn.

I would think a cracked die.

Again, if it were a cracked die, it would not extend over the rim of the coin. It would end before the rim.  Note on this image how the die crack ends before the rim on both sides? I looks like it maybe a thin line of glue. Note how it flows over the edge of the coin at 2:00 on the last image? Edited by coop

Probably next question would be, is there a scratch on the top of the raised area? Do you see gray anywhere on this area?

Its definitely over the rim and on the one by the date it kind of forms a small mass/blob on the rim itself  |

Excuse me but why do you think a die crack can't flow up and over the rim?

I can see Conder101's implication...that a crack in the die can, or should be able to, go to the outer circumference of the die. This would mean that it would include the shoulder on the die which is responsible for the inside portion of the rim. (I am not completely comfortable with my understanding of the morphology of a die, so I may need correcting here.) This would mean that a crack should be able to show at least to the approximate center of the rim (or that portion of the rim which is not attributable to the portion of the rim formed by the upsetting process.
Comments?
