Does this rotated reverse give this coin any added value?   |

I would think so but I don't know how much. John1  |

It does and I dont know how much. My recollection is that 15 - 20% rotation increases the premium. 30% is substantial. Yours looks closer to 45 degrees reverse (to me). Nice coin. Check out this website http://www.kennedyhalfdollar.com/er...ed-dies.htmlEdited by j_h_s

I would say that rotation is closer to 60 degrees then 30 degrees. I have not seen a modern US coin with that amount of rotation personally. I think it is worth more then $0.50, though what exactly I could not say.

I think it is worth more then $0.50, though what exactly I could not say.  That's closer to a 60 degree and that's a substantial rotation to an error collector, in and of itself. I don't know that I'd call myself an "error collector" (more like an "enthusiast," in that I wouldn't throw a good one back should I find one), but I think I happen to know enough to at least know that. If it also helps, I don't think I've ever seen a Kennedy rotated that much, and certainly wouldn't expect to see one in as recent as an '88. So, good eye, good find! PS: Tell you a simple method to estimate the degree. Take out a Kennedy 2X2 and mark it with a pen from 0 to 90, both CW and CCW. I just then split that for the 45, then split again for the 22.5 and the 67.5. Then, line up the coin and see. |

Actually, I think the angle was calculated from the horizontal plane, not the vertical plane. Calculating from the vertical plane would, of course, make it a 60% CCW rotation.

You calculate from the Y-axis, that's right. And 90 - 30 does = 60.  |

The holder was flipped over for the second picture. These are fairly "common" in the '88 mint set affecting about every 140th Philly half. Some are fully 180 degree rotation. I would think it wouldn't be hatrd top get 4- or 50 dollars for one like this but you might want to check ebay. Time don't fly, it bounds and leaps.

CoinMeister, Cladking knows his clads, that's why he's the king. Cladking, don't mention it. Needless to say from now on I'm going to be taking a second look at the '88s I find in my rolls...

Nice find.I would think that the newer the coin is, the less likely of you finding one rotated like that.Just a guess though.

I did an ebay search with the words Kennedy half Rotated. There were no results in current listings and only 1 result in the ended listings It is a 1982 but it is not much of a rotated reverse (see link). Maybe the 1988 with a 60% rotated reverse is not all that common. http://cgi.ebay.com/1982-KENNEDY-HA...em3efedc0f5a |

Yes, forty or fifty dollars.
I believe that's 30% rotation unless you want to measure from the opposite direction then it's 150%. Since the reverse picture is upside down you have to use a new reference to gauge the rotation.

The reverse picture is not upside down. That Eagle should be straight up when the coin is flipped over. Instead, the Eagle is rotated about 60% CCW. If it were another 30% CCW, it would be at a 90% angle. |

If it were another 30% CCW, it would be at a 90% angle. Note the missing staple is on the top of the holder on the first picture and the bottom on the second. This means the holder was flipped top for bottom for the second picture so the coin should be right side up. Since it is off about 30 degrees I believe this is defined as a 30 degree rotation. Am I missing something here? Time don't fly, it bounds and leaps.

It's quite likely that all the rotated reverse '88-P half dollars went into mint sets so we can get a very good estimate of the mintage on these. Figure about 12,000. Probably about 4,000 have been lost to fire and flood and the like and another 1,000 have been cut from the packaging and sp[ent or otherwise degraded. I'd guess there are about 7,000 pristine examples (though these don't come very nice) and about 600 sitting in bank rolls.

Nice find. I guess I'm gonna hafto check all my halves from now on. BIG PROBLEM- my area banks never have any!
