That's quite the undertaking, but all the best to you. I am very new to the CGC game (just waiting for my first issues to come back to me, they are in the "scheduled for grading" category) but have loved and followed comics for years. As a vet I get a little perturbed at the whole Variant Cover game (Star Wars was INSANE!) but then of course I see the Campbell Variant Cover for Extraordinary X-Men 1 and all I can think is "I HAVE TO HAVE THAT!". Anyways, I'm going off topic, good luck on your collection. The Ditko and Romita covers POP so nice when you line them up!
