Lincoln die rotation

Here are 2 photos crappy but you can see the rotation

Nice save on that one. I'm guessing around 20 degrees.

 

Thanks for the link; I bookmarked it!

 

Your telling me haha only reason I saves it was because it was counter clockwise.

 

You still have me thinking about this..funny

 

Yea I still take a glance at it every time I can lol

 

Thanks for a great topic that had me wondering for a while. I'm new to collecting and this information is a definite plus. Thanks soooo much. Gary C

 

Look at the 1972 DDO varieties. For several it is the direction of the rotation that reduces the number of possibilities. Probably the best example I am aware .

 

This is way different from all machining standards - CNC. 0 degrees is straight out to the right. Is the mint out of sink with the rest of the world? Oh ya, that's the government!

 

I think you give the degree of rotation, then the direction of rotation. Otherwise, something rotated 5 degrees out of line could be 355 degrees out of alignment, depending on direction.
And since U.S. coins are aligned by coin rotation, they start out at 180 degrees.

 

Yep, agree...15-20 degrees ccw.

I'm not certain, but I read somewhere a while ago that a 10 degree rotation was within tolerance. I am not sure what the actual parameters governing rotation are, nor am I cognizant of values associated with "out of tolerance" rotations.

I am off to research...

From Numismaster.com, under "News and Articles", is an article titled "Rotated Reverse Confuses Collectors". It is submitted by Alan Herbert from July 11, 2011, and was originally published in Coins Magazine.

In the article, Herbert states the mint tolerance for rotation is 7 degrees.

So there, presuming the info is correct, we can say that 8 degrees is a minor difference and worth a minor premium. Correspondingly, the maximum rotation is 180 degrees and is considered a "clockwise" rotation. Using this rule, that would mean the maximum "counter-clockwise" rotation could only reach 179 degrees...and, of course the premium escalates with the degree of rotation.

I don't have any examples of degree rotation to premiums. Collectors would have to do their own due diligence and research to find how much a certain rotation variety sold for, along with the usual grading parameters, including differences of denomination.
