Very nice error, but tell me why it is worth almost 200. How does this kind of error occur? As it seems that if the dies are rotated there would be several thousand of these out there. Or does something else happen?????? I have seen many older Modern proof coins with this variety, such as Jefferson proofs from the early 60's. Anybody got an idea??
I seem to recall there was a rotated die Kennedy that made it's way into a "non top tier TPG service" slab that was actually a "trick coin" you could by in a magic shop?
I think Eric owns it or has seen it.

It should be called a "rotated die error" rather than a "rotated reverse error" because it is impossible to determine whether it was the obverse die or the reverse die that rotated.
There are at least three potential causes for rotated die errors.
1. A loose die that is rotating in its socket. In this case there may be many rotated die errors produced by the press, but they will all show different amounts of rotation. I know of several progressions that show varying degrees of rotation, including 1988-P half dollars. There are also multi-struck coins that show rotations between strikes on the obverse face.
2. A die that is incorrectly installed. Here you would expect numerous identical rotations.
3. A die that is improperly prepared so that the installation guide (the "flat") is ground in the wrong place. Again, this would lead to an identical group of rotated die errors.
