Dc comics pricing on 1965 action comics?

The value of old comic books varies wildly. It depends on their rarity, condition, and desirability from collectors.

A quick way to gauge value is to look at auctions on eBay to see what people are selling the issue for. Be sure to look for actual sales, not just listings. Note that condition can greatly affect price: you may find the same issue listed for anywhere from a couple of dollars to hundreds of dollars.

The Overstreet Comic Book Price Guide is widely considered aprimary authority on the comic book pricing and grading.
