Yes I know. But I think that is due to the excessive die polishing. Wouldn't be the first time I was wrong though - wait for more opinions.
Looks like it might be Die Deterioration as well as excessive Die Polishing! However, I have seen some Jefferson Nickels with similar striations in the fields and on some details that was apparently due to grease. Frank
Yes! Although it may not have any additional value over a normal 1983-P Kennedy Half, it is still collectible and a nice conversation piece. Frank
