That makes sense, on the other hand, there's zero risk associated with T-bills, and more-or-less predictable risk associated with stocks (at least if you're properly diversified), whereas there are really only guesses as to the risk associated with baseball cards. (Notice, for example, the frequent speculation around here that this is all a bubble. I'm not saying that it is, but there are lots of serious collectors on Net54, and no consensus that this isn't a bubble.) Also, baseball cards don't pay dividends, you've got to hope that prices continue to increase.
