I have in hand a number of “Challenge Coins” which I’ve been calling “Mystery Coins”, by which I mean coins which I’ve flipped, meaning spent more money on than the penny originally called for. But why did I flip that particular coin? It’s a Mystery. YOU have to guess/decide/see what it was about this coin that prompted me to spend good hard cash on it over and above its 1 cent face value. Why plunk down more money on a worthless coin??? Obviously, because to me, it’s worth more than a penny. But why? And how much more?
