Die rotation on proof coins.

[cpm9ball]

My roommate received some 70's & 80's proof sets from his 96 year-old mother. He had no use for them, so I bought them. I noticed that several of the Jefferson nickels had a rotated reverse. It's only about 10 degrees, and this is probably within the normal tolerance for business strikes, but is this common on proof coins of that era?

 

Thanks!

Chris, I believe I read that 20 degrees is the minimum for them to consider it rotated? But I know 10 is within tolerance.

I've also heard that below 15 degrees is tolerable. Looking at my Jeff Dansco Chris, about all my proofs are rotated to some extent all the way thru the 80's and even into the 90's.

I posted this set in '08 some good responses. It was the half, not the Jeff.

Woody, thanks for bringing this forward. Did you ever submit that Kennedy for grading?

According to Alan Herbert, the Mint tolerance is 7 degrees for each die (14 degrees total), so anything under 15 degrees is acceptable. However, I was wondering if proof production might have stricter standards. Herbert doesn't address this, so I guess it is the same for proofs.

Nope, but I did write a note and stuck it in the OGP...if the opportunity arises, that don't happen to often anymore, it might, but I'm keeping an eye out (old pirate joke) for anything similar being sold that would warrant the expense to get it holdered.
