Ugh I hate when the scratches on the holder ruin the picture. I'm going to say MS66RB but I'm hesitating over BN or RB.
That's all on my. I took horrible care of my slabs. it's a pretty blue though, like many others I have.
Ok well you should buy a 50mm F1.8 lens. That might sound like a load of jibber jabber, but the F1.8 bit is the most important. Basically, the F number is the aperture, or the size of the hole in the lens. This regulates how much light goes into the hole. The bigger the F number, the smaller the hole. So, F1.8 is a huge hole. Anyway, the bigger the hole, the shorter the depth of field, which is basically the width of the field of things that is in focus perpendicular to the lens. Anyway, at F1.8, the depth of field is so short that if the coin is in focus, nothing else in front of behind is in focus, meaning that the scratches will not be in focus and therefore will not appear. The Yongnuo 50mm F1.8 lens is a good cheap one for only $50.
