1982P Large date rotated die

What if the hammer die rotated slightly in one direction and the anvil slightly in the opposite direction. Then how would you describe it ? Nice rotation.

That is not how rotation happens. The rotation occurs when one or the other die is installed in a rotated position in respect to the other. In other words, it does not rotate with time or use.

Congrats Roller! Very nice rotated die find and a very informative thread! Thanks for posting it!

Nice find... Look at the rotation this way - From the west to the east (left to right) draw a horizontal line using the base of the letters in LIBERTY... When you flip the coin to the rev draw a horizontal line across the memorials base from west to east... If the west tip of the base is up from the obv horizontal it is a CW rotation from 0 to 90 degrees and if the east tip of the base is up then it is a CCW rotation... If it is a 180 degree rotation the point is moot... In the case of this coin it is a little difficult to tell... In the pics of the coin in a 2x2 with staples the obv pic has a staple, on the east side, that runs SSW - NNE... On the rev pic the staple in view on the east side appears to be N - S which throws off the measurement for me any way... The best I can tell is CCW about 65 - 70 degrees???

I thought that sooner or later the staples position would be addressed. LOL. The staples were not applied in strict vertical and horizontal order. So, for clarification here are some shots from an evolving methodology for photographing the anomaly. I don't see a 65-70 degree rotation.
Referring back to Ed's and mine agreement that all rotation is either 90 degrees or less or 180 degrees, how do we get to all the rotations reported on the Lincoln Cent Resource, for instance, in the many 160, 120 etc. rotations. The only way is that they measure rotation in the clock wise direction from the obverse die. In that case, this is a rotation in excess of 90 degrees.

And then some!

all rotation is either 90 degrees or less or 180 degrees,

It's less than 180 or medalic orientation if 180.

Just take the degree number that's less than 180.
Think this way.... so your coin is 70 out one way and it's 290 the other way so you call it 70.
If it was 160 out, it would be 200 the other way so you call it 160.

Isn't that right?

The only problem I see with your numbers is the assumption of having 360 degrees of rotation available... There is only 180 degrees possible... If you rotate the die 360 degrees you are back to where you started... I hope that makes sense???

[jfines69]

Yea those staples got me I guess the angle of rotation depends on where you begin... To me it looks like an 80 degree CW rotation... The west corner on the base is up correct???

That is true but since nobody can tell which way it rotated, it can only be assumed to be the number of 180 or below. If that wasn't true then every 10 degree rotated coin would be considered 350 degrees out.
