Most underappreciated/undercollected players

[phikappapsi]

Hey fellas - this is probably a topic that's been hashed out on these boards a few times; but who doesn't like circling back on old conversations?

Just curious if anyone has strong feelings about guys they think are just massively undervalued, under-collected, or underappreciated in the hobby relative to their contribution to the game.

For me; I've always found it curious just how small the premium is for Rogers Hornsby. Maybe just the era he played in was that gap period that seems to exist between the Tobacco and Gum card waves? Or maybe he's just not a name that gets enough play in the history of the game? But one of the greatest pure hitters in the history of the game, right there in the conversation with Cobb and Teddy, but seems to get very little love.
