Nice site! I like how it pulls from various sources and, so far, has a good variety of topics. I won't click on all the links, but it's good that you provide a summary of what each link will give you. Great touch on adding the reading time in the summary, too. Personally, compilation lists like the '30 Rarest Action Figures' and the '15 Geek Collectibles...' I love because they're quick snippets.
Cards and toys are big collectible categories in my world, but I do have an interest in reading/viewing many things pop culture, so as long as you keep providing those articles, videos, I think you'll have a decent following.
At the beginning, it's probably good to add a lot of different collectible articles, and keep an eye on how many people click on each one. I'm sure after some research, you'll be able to thin out the categories to the ones that your readers care about the most.
Good luck!
