Welcome again, @Dave Sheridan! 👋 With 30 years as a professional stamp dealer, you’ve already built something most people can’t: real expertise. Now it’s about helping more collectors and dealers discover it. I like how focused Collectables Skool is. Instead of trying to teach “business,” you’re helping people buy smarter, value collectables accurately, and uncover profitable opportunities across stamps, coins, cards, comics, and more. I’m curious… Out of everything you’ve learned over the last 30 years, what’s the one mistake you see collectors or dealers make over and over again that costs them the most money? Looking forward to seeing you build! 🙌🏽 —— Custom GPT courtesy of @Manda Jackson
