422. Mourning Track Power
Buying up cards of a very old former player, for the sole purpose of selling them at exorbitant prices on the gigantic bubble that will surely come after he passes away.
In the last few years, cards of every all-time great who had suddenly passed away skyrocketed in value. Add to that the sheer legendary status of
'The Say Hey Kid' and you better buy now while the (overpriced) getting is good (not as badly overpriced as it could be).
Again, not happy to be a realist here.
