I have a handful of historically significant silver age Fantastic Four books. Some were a family member's who purchased them new in the 60's. Others I purchased at comic book shows in the 80s when I was actively collecting. I do plan on selling them eventually (fingers crossed that Marvel eventually puts together a good FF film).
Below are the books that I have and their general condition. I'd appreciate some advice on if these would be worth getting graded and, if so, some help with prioritizing them. I've never been through the process before.
FF #6 - Marvel's first villain team-up (Doom & Namor). This one is in the worst shape. Although it is completely intact and readable. The cover near the spine is faded a bit.
FF #15 - Similar condition to #6. Maybe slightly better. It doesn't have as much cover fading; but, the spine is slightly rolled.
FF #10 (Spanish language version) - This one was purchased in a mylar sleeve and has been kept that way. It is in much better shape than the previous two. I just bought it because it was in good shape for an old book and, at the time, I liked the Spanish cover (Los 4 Fantasticos...LOL).
FF # 48-50 - The first appearance of Galactus and the Silver Surfer. My uneducated grade from 1-10 on these would be around a 5, or so, for #48 & #49. #50 is in better shape than the other two and has always been in a mylar sleeve. I would give it at least a 7. Maybe slightly higher. Again, these are my uneducated grades...not to be confused with official grades.
FF #52 - The first appearance of Black Panther. It is in similar shape as #48 & #49. Probably around a 5, or so.
All of them have been kept in regular bags and boards (except the two in mylar) since sometime in the 80s. Besides having them graded, I like the idea of preventing any further degradation. I can add pics if that would help. Any advice would be appreciated. Thanks!
