Kennedy Half dollar rim issue

Interesting rim issue. I’m fairly new to error coin collecting so not sure what the error is here or even if it is an error. Thanks for any input!

Hard to tell from pictures but there appears to be die fatigue associated with your coin's strike. Better pictures are needed including one from the obverse.

Hope this helps, thanks

that is what i usually attribute that gully around the rim and other devices to, die fatigue. there are some morgans with this effect, especially on the rev that are VERY neat imo.

iirc, these effects usually spawn from improper tempering, basining etc. there is some good material out on the subject, spread across a few sites/forums.
