What is this kind of error?

Do they mean alignment error?

It's a very popular rotated reverse error that should fetch upwards of $1000.

Why don't they say rotated reverse??

Why don't they say rotated reverse??

Because the rotation is very signifigant - both sides face the same way if the coin is rotated, like on a medal. (Hence the "Medal Alignment" designation). In other words, it's far more signifigant than your regular run-of-the-mill rotated reverse.

Coin books refer to these type of errors as rotation errors not "Medallic Errors".

This one would be refered to as 360 degree rotation error.

[kryptonitecomics]

Wouldn't it be 180 degree rotation?? If it was 360 degrees than it would be a normal reverse since it would rotated complete around to it's proper alignment

This is a widely known and popular modern variety (error to most purists). They normally go for far more than $115. The hammer dies (obverse) occassionally will shear the pin holding them in place and drift according to the forces generated by the succession of deforming planchets under them and other stresses in their cycle. Due to the nature of coin design they have a tendency to achieve a steady state at 180 degrees. Medals are frequently designed with the orientation identical on each side so this is sometimes referred to as medal rotation. All modern rotated dies can be found with various rotations and generally the most common is 180 degrees.

 

There are even two of these available in mint sets. The first is an extremely rare 1965 half with 180 degree and the other is a 1988-P half with 180 degree. The latter has an incidence in excess of .5%
