There are a lot of places to find such valuable comic books for collections. There is of course the Internet where one can pretty much find anything from all over the world. eBay and other online auction sites are the best places to find rare and sought after books. One just has to make the right offer and pay for shipping. Classified ads like Craigslist.com may also have these comic books.

Another place to find DC comics books to add to your collection are Comic Conventions like the one they hold every year in San Diego, CA. There are people there who sell their stuff. Other collectors can also make trades. One good thing about ComicCons is that you get to meet people who share your interest. You can share information and experiences with them, and who knows, maybe they can help you find good stuff for your collection.

There are also comic book stores everywhere. Not only do they sell newly distributed comics, they also sell old comic books. They may sell something valuable to add to your collection.

Flea markets and swap meets are also good places to find rare stuff. You’re going to have to really look because a lot of those sellers will not be as organized but if you’re really patient, you may find something that will be worth a lot of money.

There are several basic points you should know and keep in mind when collecting comic books. One main thing you have to know is comic book collectors put a lot of emphasis in the condition of their books. There are, in fact, third parties that grade the condition of comic books professionally. Comic books are worth more if they are in mint condition so it is best if you seal your books, especially the valuable and rare ones in protective sleeps to preserve their integrity.
