I received the majority of these comics as an eleven year old. It was a great way to start a comic collection. Lots of different titles, but often with long sequential runs within each title.

I made a full listing of all of the comics here (note that there are two pages of this spreadsheet):

I haven't looked in detail, but I think there are a few in this collection that may be somewhat valuable. For example, X-Men 137 -- the one where Phoenix dies!

Quality varies -- they have all been read, but treated quite well for the most part. I picked a few interesting ones out for the photo, you can gauge their condition more or less from this photo.
