Sorry, but no purple labels for me - especially silver age.
I think the Avengers copy was a better deal than the Spider-man because the restoration was less intensive.
Which one would I have purchased? Well, that depends on the math. It depends on how much it would cost to have the color touch removed. Then I'd have to add on additional grading and shipping fees. It might just be possible to come out ahead.
Doubly so for the Spider-man. I'd send it in for restoration removal. I wonder what it would grade with the tear-seal removed? Once again, you'd also have to consider the additional grading and shipping fees.
If, after all was said and done, I came out ahead with the purples, then I would have purchased the restored copies for resubmission after removal.
If not, I'd go with the blue labels every time.
I understand the difference in being a collector and an investor, but I'm the type of collector who would rather have the original intact. I'm just not a fan of restoration unless the book is extremely scarce or rare. In that instance, I favor it because the process prevents further degradation and allows the book to be preserved for future generations.
On a silver-age or bronze? Just not for me. If you want to have a copy just for the sake of having a copy at the best price possible, then I see where you're coming from. But personally? I'll take the blue label.
