Hello all!
I've been buying and selling coins for a while now, but struggle in knowing exactly what qualifies as mintstate (sometimes I think I can see wear on a coin, and then I tend to be conservative)
However, I have a strong photography background, and just got a nice scanner to get some different pics, so hopefully that will be a big help in identifying the grade!
Thank you in advance to anyone who helps! It means alot to me

Well, here's the pics, Any ideas on grades will be greatly appreciated!
