How rare are the "Firsts" of Comic Books such a Spiderman and Superman?

I've always wondered like how many there are in existence, how expensive they are, etc. Other ones I wonder about are the Incredible Hulk, and Wonder Woman.How rare are the "Firsts" of Comic Books such a Spiderman and Superman?there are no real estimates that i know of for how many are leaft because so many were destroyed over the years. you can find them but they are expensive even in crappy condition. the first superman and wonder woman are harder to find because they are older characters (1930's and 40's) where as spider-man and hulk are from the 60's
