Comic people: I have several comics from when I was in middle school. Most of them are Image. Are they worth anything? I haven't kept up with it.

From what I remember, I have:

Spawn: 1-10 (approximately)
Cyber Force: first couple #'s
Bloodshot #1
Youngblood: first couple #'s
Savage Dragon: fist couple #'s


Also, what would be the best way to sell them for the most profit? Ebay/Craigslist, local comic shop, etc.
