How about taking a fresh look at baseball card / collectible valuations? They have no intrinsic value like a security, and yet some sell for thousands of dollars and hold (most of) their value year after year. There are clearly supply and demand issues, but also issues related to the sales channel (auction houses, eBay, shows, private sales, etc), advertising and marketing (online and hard copy catalogs, press regarding "the Card" and rare finds, etc), and TPGs and trustworthiness in the transaction. There's also CPI and inflation in the background, presumably increasing the value of (at least some) cards regardless of supply. Also, I think it curious that the so-called heyday of baseball card collecting was the late 80s to early 90s, and yet the nation has added fully 55+ million people since that peak. Are there really less collectors (driving demand) today than back then? Finally, I for one would like to better understand the market segmentation (collectors, investors, speculators, registry competitors, etc) along with the various niche collectors (type card, team, player, set builders, subset builders, etc.). There are so many questions just around these topics alone. Good luck!
