Is there a more undervalued card in vintage?

[G1911]

The 1957 Frank Robinson has always seemed undervalued relative to other HOF rookies in high-printed series.

I know the obsession is with rookies, but I always think cards of good/great players in their iconic seasons are usually underpriced, like a 1968 Bob Gibson. That's cooler to me than a 1959 when he was just an afterthought in the high series.

Pre-War, guys who just barely missed the hall tend to be underpriced (Dahlen seems to be treated as a low-end HOFer now, though). Eddie Collins is underpriced, I tend to think John McGraw usually is too.
