Little did I know when I was spending a dollar to buy 8 comics a month at the local drug store in Oxford MS that they would ever be commanding the prices now seen on internet auctions. In fact, we use to laugh about the kid down the street who would pay us $5 for back issues he missed. I had all the Marvel keys as a kid, but my mother decided that her Home and Gardens were more worthy of keeping than my comics when I left for college. We still have a few hundred originals, but most are simply readers after being stored in the basement for too many years.
I started collecting again with my son, who is now a comic fanatic, before he could even read. It's a great father/son hobby, if a little on the expensive side. Still, with the stock market performing as it has the last decade, comics seem like a pretty safe investment. I tell my son that if he can keep them in good shape until he's my age, they may well be worth a fortune. Of course, by then who knows what will be fashionable, but we can always dream.
We live in ATL now-formerly NYC-and collect about 12 silver-age books, although we have yet to complete any runs. So all our collections are still works in progress. And yes, we are huge Big Bang Theory fans.
