Can't believe I'm just now stumbling upon this thread. I'm a huge Spidey fan, and have been trying to collect the entire run for a few years now.
I currently have every issue of Amazing Spider-Man from #17-689. Also have #5, 6, 8, 12, 13 & 15. So I'm only missing 10 issues from having the entire run. This doesn't include Amazing Fantasy #15, which I'm saving for last...if ever. In regards to the Annuals I have #1, 16-the most recent one.
Most of my early issues range from Good to Fine. I try to get Silver Age issues with no writing on the cover, no tears and no pages missing. Date stamps are okay, but I'm pretty picky when it comes to what I buy.
I have a few of my favorite covers CGC'd
