Ohmygosh yes! You should really look at the Big Books' publishing dates & printing numbers. He might be sitting on a gold mine!
Good luck with the kids' clothes on eBay. Clothing was one thing that I never ventured into (though I've definitely purchased a TON of my own clothing secondhand. I used to pick up dashikis from the 70s any time I ran across them in thrift stores. I was such a happy hippie...). Mostly because I wasn't any good at recognizing fakes from the real deal, and non-designer clothing didn't bring enough to get me excited about trying to flip it. 🤑
I know that sounds greedy, but I really did have to set a floor on how much something would sell for in order to be able to make a decent living. I have no idea how all the people who sell books on Amazon for a penny each manage to drag themselves out of bed and do it every day.
I was surprised to not see any other entries listed in the comments on your original post, though. Hopefully lots of folks will jump on board! Probably it's just because you gave them a whole month to get their entries in, so like me and my February post, they're procrastinating. 😆
