Comic book appraisal in/around PGH?

Hi fellow Yinzers,

I have a few (~50) single issue comics from my childhood that I was given from my parents when they moved out of our old house. I had forgotten all about them and wondered if they might be worth something (probably not), so I did a little bit of Reddit research and ended up looking at the eBay listings of similar items that had been sold. To my surprise, it seems that some of them may be worth something.

I'm wondering if anyone has any suggestions for stores or individuals that would be willing to give a quick appraisal? online resources would also be fine. just thought it was worth a shot to ask, there's all kinds of people out there lol. Thanks!
