I think that they are both fairly run of the mill MS-64s using today's standards. Years ago, they would have MS-63s. If I had to choose, I'd take the first one.
I screwed it up from the start by loading all the images at once. They are really nice in hand. As far as my original images go. It's not easy to take images of coins especially dmpl's. Coin A is 65 The 63 looks just as nice to be honest with you.
