Hey guys, I just went to a guy selling some comics for $1 and got some comics that are worth over 50. I got Crisis On Infinite Erath 1, 7 and 8, I got the first apperance of Deathstroke/Slade, Hobgoblin vs. Green Goblin, and alot more all for a dollar each. Anyway, I also got the wedding of M.J and Spider-man with him in the spider suit on the cover and all the heros and villians ready to fight behind them. Can anyone tell me the worth of this comic? and also do I have to do anything specail to get them worth the CGC price?
