Not sure of the color. Are they on a yellow-orange background or is the color balance off? All appear Bn or RB in photos
Before you get carried away with us guessing the grade, you need to learn how to crop a picture, adjust the white balance, take a picture straight on, etc. A picture of 4 coins that only occupy 30% of the picture on yellow paper does not work.
Try a white light. That would help a bit. You can get a picture twice that size. That would help. White balance!
