1958 Topps #476 is a ridiculous undervalued card, and you can get it in super high grade for well less than $300. I get that it's not scarce, but it is pretty landmark in being the first Topps Musial card after so many years of him not being in their sets. It's a beautiful card as well, and I love the back breakdown of how he hit against other teams. As a kid I had a mid-grade copy of this, and remember thinking it should be on display in Cooperstown.
