Do you have old comic books lying around that you keep because they are your favorites? Many people keep the comics as a reminder of their childhood without realizing how much money they could make by simply selling one of these books. If you collected comics back in the 50's and 60's.and hung on to them for sentimental reasons, you really should have the collection appraised. If the comics are in good condition, you may be sitting on a gold mine and not even know about it.
At one time, reading comics was believed to be the domain of children as they fantasized fighting alongside their superhero. They traded issues with their friends and most of them didn't take a lot of care when it came to handling the comic books. Today these old comic books are in big demand by collectors who try to collect entire series of comic books or investors who buy and sell comic books for big profits.
One of the main reasons for the high price of old comic books is that there are very few copies available in good condition. It is rare indeed to find one of these books in mint condition, which will fetch a really high price at auction. You don't have to search for really old comic books because some of the later books are also worth money. For example, a copy of Buffy, the Vampire Slayer costs about $20. Although this may not seem like much when you compare it to the hundreds of thousands of dollars paid for a Superman comic book, if you have enough of them, you have a sizeable amount of money built up in your collection.
Old comic books are now the domain of adults. Many of the books purchased are never even opened so as to keep them preserved. Those collectors who do spend a lot of money buying old comic books hope that the value of the book goes up and that they will realize profits from their purchase.
