I have seen quite a few so I know they aren't really rare unless it is major, but which ones are keepers when they are just above minor off strikes. Only when the back is off struck also? I have a cute little mis strike that has some of the bottom of the date missing, very lightly struck, I like that one so I am keeping it, but what is your general keepers??
If the back (reverse) isn't struck the same "off center" as the front (obverse) then it's a misaligned die, see http://minterrornews.com/glossaryoffcenterstruckcoins.html
