Maybe with the exception of Mantle, I think you can't just stop at naming a player. IMO rookie cards, early cards, or relatively low pop cards have more relative upside than later, common issues. Assuming you're buying at today's market price -- a big assumption because lots of people including myself haha tend to overpay -- I think well centered cards and mid to high grade cards have more relative upside than not so centered and lower grade cards. So if one is really buying to "invest" I don't think it's as simple as saying Mays is a good investment and Spahn isn't.
