I used to have Star Wars #1 from the original series in the 70's, and others. Sold all my comics in the 90's and early 2000's.
It's hard to hold onto boxes of comics when moving across the country, though there are a few I should have kept, especially Hulk 181 first appearance of Wolverine. I still like going to comic stores and looking at the old ones, if I got back into it I'd just start buying the older and rarer ones, because they always seem to be in demand and go up in price. If I'd known better in the late 70's and 80's could have been a millionaire easy on comics and sports cards by buying and holding the right ones.
