For my first time ever, I am sending a comic in to be graded. I am also just learning about the whole grading system so my level is definitely newbieish. What I have is a Darth Vader (2015) #3 Fourth Printing. As I am exploring the CGC site, I began looking at the "Collectors Society" and other collectors collections. When I clicked on my comic within a collectors set, it looks like there are over 40 variations. What are the A-1 thru A-5, B-1 thru B-5, C-1 thru C-5 variations? There are also "Apparent" versions with different letters at the end. And then SS A-1 thru A-5, etc. Do I even need to worry about which variation my comic is or does CGC determine that when they go thru the grading process? Any help is greatly appreciate. Thanks for your time!
