If obverse and reverse are not opposed 180 degrees(normal coin alignment), then you have a rotated die strike. If the obverse and reverse designs are not centered to each other, you have a misaligned die strike.

Are you talking about when the reverse of the coin is rotated or are you talking about them being off-center as in parts of the design are missing or close to missing?
There's a difference.

If the obverse and reverse are misaligned. It needs to be over 15% off to bring a premium.

It is called "Die Axis Rotation"
For most collectible coins the degree of rotation (between obverse and reverse) should be a minimum of 90 degrees. 180 degrees is the big one.
Not that some people may be interested in a lesser rotation, say 45 or so. Being that most coins are round that makes an easy template for 360
degrees. Find the northern center point of the obverse (coins differ some naturally as to that location exactly) Make a true north to south line and then figure your degree of rotaion compared to the reverse.
You can use a template or a compass also to find it. Some align the coin the best they can in a coin flip and then you can just flip the coin over and see the difference and measure it. I'm sure others will chime in with their own ideas etc.
Hope that helps some.

you may want to keep this one in you're records, it's pretty common to find (depending on what you mean)
a MAD(misaligned die) where one side is centered and the other is not(common error, easy to spot, easy to attribute)
an Off-center strike is where both sides are "cut off" the coin
(less common error, really easy to spot, really easy to attribute)
and a rotated die is when the obverse or reverse is not in the proper alignment (coin alignment or medal alignment) than normal
(harder to spot[only hard because of the pictures needed], harder to spot, harder to attribute)

LOL - I just wanted to make sure you didn't have an off-center rotated die and cue the fruit! Just put it in a 2x2 as straight up and down as you can, then flip it end over from a N-S direction, then take pictures.  |

I always found Scooby's suggestion to be the best for me - use a flip or 2x2.
Because I use a "stick" to search coins, if I put them all on the "stick" in the same alignment, when I flip the whole thing over, anything out of alignment will show up - it will be the one not facing the same way as all the rest.

 You could get out your old grade-school protractor and measure the angle that way. Or, give it a good guesstimate, most rotated dies are rounded up. You rarely hear a 14 degree rotation. |
