1962, 1963 Proof Jefferson Nickels

Hey all,

Stumbled upon this pretty pair in a box that also included a slick Buffalo, some nice 50's, two War Nickels, and a '39 (no idea about what type). The 1962 was actually an ender too. From what I've researched, 60's proofs are common but it increased my collection to 3 so I'm pretty happy. Anyway, just wondering what kind of grade they would rate. The 62 is practically flawless when I look at it, but the 63 has some damage along the rim and a bit of gunk on the reverse. Also, how would you tell what a cameo is and what is the difference between a cameo and a deep cameo? Thanks.
