Comic Books

I would recommend going through eBay and seeing what they are selling for so you know what you should expect (store will probably give you half of what you are seeing on eBay so that they get a profit). You could also see what they are selling for on mycomicshop.com or what they are valued at on comicbookrealm.com (this tends to not get the spikes of current hot titles, but that won't be the case for most of yours since they are older unless they are an obscure first appearance that is now going to be in a movie/TV show).

If you want to do more work, you could try selling them on eBay yourself. Or there are Facebook groups where people sell things that generally get good prices and you don't need to pay eBay fees.

Let me know if you have more questions and/or want me to glance at your titles.
