Best to post one coin per thread, easier for everyone. I see no doubled dies at all, as Coinfrog said, looks like a lot of Die Deterioration. That being said, with the pics provided (need to be clearer), coin number 4 looks like it could be RPM-003, on Variety Vista, pic comparison below. Coins 5 and 6 show promise with something going on inside the mm. There are a pile of RPM's for this year so I'm letting you study those, with the link below, get back with us on your thoughts. Remember, you can rule out most by the mint mark location to the date.
