1976 Silver Proof Error, Severe Rotated Die,?

to CCF.Give it a little time it's only been a few hours and the pros are probably still asleep . You have some cool pics in your link by the way.

Fair enough :) Thanks for the welcome and nice to meet you. I've always been drawn to the Early silver US commemorative coins. How about yourself, whats your fav?

Better photos, please!
Kennedy half proofs exist with rotated die errors so a rotated bicentennial quarter proof seems possible. There are however fake errors made by machinists (I have several Kennedy examples) so your coin should be examined carefully. Check the weight; machined fakes will probably be too light.

If genuine I expect it could be worth $200 or more.

It would be harder to fake one of these on a proof because the mirror surface would be so easy to mar. Look carefully under magnification for a seam just inside the rim on either side or around the edge.

Thanks for the feedback folks!

When I took this coin to a dealer years ago, who was into error pieces, he also said the same thing about it being more of a curiosity piece rather than an error coin. Please help me to understand this.

A proof coin is valued for its exceptional perfection, It is checked before packing for any flaws so an error proof would be far rarer than a circulating error wouldn't it? So wouldn't those circumstances make it even rarer and more valuable of an error since the number minted is lower and the quality standards are higher?

Yes they are checked, but they aren't really checked that closely (Ask all the people who are constantly complaining of receiving proofs with spots and nicks.). And they might check the obv and the rev,but they aren't too likely to check the orientation between them.



Yes, but the circulation coins with rotated dies are usually worth very little, so even if a proof is worth two or three times as much, three times very little is still pretty small. Also you have the problem of finding someone who is interested in it
