I think its 3,5,and 7. however, I don't feel that any of the cleanings are recent. It is difficult by photos.
My guess is that they all have been cleaned at one time or another. Some may have been cleaned a long time ago so do not appear as cleaned. But I still think at one time or another they were all cleaned at least to a moderate amount. I base that on so many coins are cleaned in the past just because they looked dirty. I remember when I was a kid I used to clean Indian Head Cents I would find in change. This is way, way back in time you know when such things were still in circulation.
