When looking to collect all of Spidey's rogues appearances, what method did you use?
There are dozens and dozens of them and most of them are under issue #20.
I feel like a fair estimate is save $200-250 and get the best possible grade. This could net mid-grade appearances of Kraven, Scorpion, and Kingpin and high grade copies of Venom, Carnage, Morbius, and Hobgoblin. Obviously
When it comes to issues 14 and under, it becomes so much more expensive, first appearance included or not. I must have those issues at some point as a collector, but the task seems so difficult.
