Could use some/any suggestions on what this is or how it happened. I THINK it was maybe a flawed planchet then struck?,as the line is incuse into the nickle but the word "LIBERTY" is struck perfectly over the incuse line. In the pics the line/groove looks black compared to the silver color of the coin and arrows point at it. Any thoughts or opinions will be greatly appreciated!!
I'm posting merely to learn about what everyone thinks. I've never seen something like this; I'm thinking part of the die broke off?
What we can guess. 1. The die that struck the coin is not broken. 2. Something did damage the die that struck the coin. 3. Whatever it was, it was probably curved and damaged it twice. a. So a remnant of a previously struck coin's "fin." b. a circular chip off the collar. c. a curved wire. d. the raised edge of another coin.
I'm just wondering if it's cud related since it's along the rim. Like Insider said, Mike Diamond would be the go-to guy. You might find something here. http://cuds-on-coins.com/ If not, send them a picture of your Jefferson. If they don't know the answer, I'm sure they could head you in the right direction.
Thanks - still learning and not with error coins . I did narrow it down. Cannot think of anything else to cause this.
Thanks Tom - but I thought a cud was a part of a broken die around the rim causing a raised metal anomaly.
I meant Incomplete Punch - This is what I mean by that - I want to share this webpage with you http://www.error-ref.com/incomplete-punch/
Well yes.. the Incomplete Punch would be on a blank planchet. Then the blank would be struck and the raised letters over the incused area.
Still just wondering - wouldn't the die strike fill in the void on the planchet as it produced the upraised letters??
