Tangential to this thread…
First off, what is your most sentimentally prized physical possession, excluding humans, but including pets/animals? Secondly, how much would someone have to pay you for you to sell it? Or would you not part with it, even for hilariously obscene sums? And how does that amount compare to whatever market value it has?
(One rule: once you sell it, it’s gone… you’ll NEVER be able to buy it back, no matter how much influence/power/wealth you end up with.)
For me, it’s probably the ticket/entry checkpoint from when my great grandparents brought the family from Eastern Europe to Ellis Island in 1911 or so. Right now, I have no pressing financial needs, but I’d certainly sell it for some amount, probably around 80 or 90 thousand dollars… enough to put in mutual funds and eventually pay for a child’s college education. My family, living and dead, are practical people who value education, and would not be bothered by that decision. I can imagine my price dropping quite a bit if I were in financial need.
