Thanks, should I remove the staple at the top? Unfortunately I do not have smart phone that has the function. It there someone that I can send it to for attribution? It does not appear that the rotated die website offers attribution services.

Funny I was going to post same thing about a Morgan dollar with about the same rotation tonight. Yours looks to be rotated about 15 degrees counterclockwise. That is if I am reading the rotation tool info on my photo software correctly. Edited by MontCollector

Thanks John, I have had on many LC's about that degree of rotation CW but didn't know is was also common for the CCW. I appreciate the info.
MC - That is a nice looking Morgan. The rotated dies website only lists 90 degrees or better though. Hopefully someone in your classic forum has more info on them.

Nice coin. I have a question. When you flipped the coin to the reverse, did you flip it left or right, or up or down? If you flipped the coin from the obverse to the reverse left or right it is very close to 180 degrees full incorrect rotation. If you flipped up or down they are right with it being 15 degrees ccw.

Thanks MS70, I never even thought to flip it left or right (it looks way different that way). I flipped the original up and over. Here it is flipping it to the left - very cool learning this.  |

Yea it's cool and shows why the direction of the flip matters when determining degrees rotated. A US coin is meant to be flipped end over end (up or down) so that when it is flipped that way the opposite side is not upside down. Just the opposite happens when you medal flip (flip left or right) a US coin. When flipped left or right, the opposite side of a US coin is upside down. But as you see from your pictures it is rotated slightly but a noticeable 15 degrees or so either way you flip it. I learned today though that when determining clockwise or counter clockwise rotation on a US coin to flip it end over end (up or down). I just asked what direction the flip was bc it wasn't stated and would be the difference between 15 degrees rotation or 165 degrees rotation.

I have a holder that has lines all over it, each one is from the center of the holder to the outside edge of the holder. The middle line going straight up and down is marked 360 at the top and 180 at the bottom, the others are marked accordingly. I can pick a spot on the outside edge of the coin and rotate it, then count the degrees I moved it. Maybe I should get a patent.
It's good for rotations, and if I line up trails with a particular line, I can read the offset direction.

That sounds great. The rotated die website has what they call a Rota-Flip (but they are sold out). I have looked on ebay a few times now trying to find something like that with no luck. |

In Vol 25 No 3 May/June 2016 "Errorscope" Ken Potter on page 24 details how to use Photoshop to measure the rotation. I used Irfanview or Gimp to get the same result, any image software that has a rotation tool will work.. Image or scan the coin in a holder making sure it's straight. On the Lincoln Cent "LIBERTY" should be perfectly horizontal. Flip the holder 180 degrees. Rescan or image open your new image and with the rotation tool rotate the image until the Memorial is horizontal. Depending on the software your are using you may have to type in a number to rotate. Other software like ( Gimp ) tells you the angle as you rotate it with your mouse. |

I put it in Gimp an it's around 10 degrees. Both Gimp and Irfanview can be loaded from the WEB. Last time I looked they were free downloads  |
