You started a few years sooner than I did, Bob. My dad bought both my brother and I those Whitman Lincoln Cent folders about the summer of 1956. I would have been eleven and my brother nine. I still have my first volume, but I had to replace the second one when one of my dogs decided he needed to cut his teeth on it about ten years ago.
Sam Walton himself offered my grandparents 15000 shares of Walmart at $0.50 per share at the initial public offering. They turned it down to buy a house instead. The stock would have been worth over $200 million in the 1980s... But I think I am happier with how I came out from a lower-income family than if my family were millionaires.
Yes, your observation of being a millionaire, as was our illustrious leader. Who's given a large stipend, seemingly wanting to learn the rules of bankruptcy. It worked for himself and others. "Investing" in coins can result with a large deficit. You may have good luck if you first learn about "collecting" what others desire, and how to acquire. JMHO
