Good question and I'm unsure of the answer to your question. I do like the slight MAD on the obv.

I'm not referring to just the one jagged line. There are what looks like 10-12 ridges.

These lines appear to have their start within the letters of IN and terminate somewhere above the letters of WE. The arc that creates would not have its axis in the center of the coin which is where the axis point would be if they were lathe lines. These appear to be something other than lathe lines

Thank you Spence. I researched a little and they don't really look like Lathe lines. Not sure what it is.

I agree...Wondering if it might be a planchet issue.

Lathe lines are circular in shape:

Note how lathe lines are consistent? On the OPs coin they are not circular, all varing in strength. Looks like die damage. The fields are the areas damage to a die is usually shown.


The die was not finished off to remove these fine lines before the die was hubbed, so they remain on the die and transferred to coin struck by that die.

It could an area partly worked over to polish the die, and didn't finish, or thought it was not able to be fixed and gave up and used the die like it is. Figuring: "No one will notice?" While this look like a large area on the image, it is actually small on the die. We are looking at it through a scope.

It appears to be some form of peripheral die damage. If it was a planchet problem, then it would be most obvious along the tops of the letters, where effective striking pressure is lower. Instead, it is absent from the tops of the letters. This indicates that the curved lines are restricted to the field portion of the die.

Thank you Mr. Diamond for taking the time to look at this. Thinking this could be the result of a few off-center strikes ?

Unlikely, since the die is much harder than any cent planchet. Most cases of die damage cannot be assigned to any particular cause.

More likely a serious MAD that banged into the edge of the collar opening a few times and was quickly reset properly.

Yes--MAD is the term I should have used. The die would be MAD as well if it were an animate object. (Getting beat up like that)
