Is this an off strike???

MSD61

I got this 71-D Ike today and noticed at the top part of the coin from say 10:00 to 2:00 this ridge that kind of looks like a slight off strike. I made the images as big as the forum allows so that maybe someone can tell me what this is. It's only on the obverse of the coin.
Thanks!!!

I have one just like it. A little more pronounced but it looks the same. It would be interesting to know also.

Hey Trooper,
Well yours really looks like and off strike. I think mine is too but not to a great degree. Oh well, it stuck me as interesting!

I believe that is a misadjusted die and not an off center.

Looks funny. Grind that off with a dremel or somethin' so it'll look right, will ya?
Dang mints. No pride in workmanship I'll tell ya.

Really it's nothing other than normal production. What has happened is that the collar has stretched slightly and the edge of the Ike is out a little farther than normal because of the stretched out collar.

Thanks Dog97 I was wondering what it was.

I very strongly doubt that the collar was wider than normal. The vast majority of coins that show this effect have a diameter that is perfectly normal. Yoy could always measure the diameter with a caliper to test this idea.

This appears to be an example of "finning". Due to abnormally high striking pressure, or a slight degree of die tilt, metal is forced into the narrow gap between the die neck and the collar.

I see no evidence of a horizontal misalignment. It's certainly not an off-center strike.
