Bought this Koufax raw on ebay. I didn't notice the tilt until I had it in hand. It's not huge and I still think front centering looks great overall. The card itself is really sharp and clean. The back is WAY OC, but it doesn't seem like that's even a consideration as long as the letters aren't cut off.
It should get high grades for surface, edges, and corners. Does the tilt knock it down a ton or get a qualifier? Because the other aspects are so great, I'd ask for a qualifier grade if the tilt would otherwise kill the overall grade. What do you think?
Also, this is one of the nicest-looking PSA 5's I've ever seen. The corners aren't perfect, but they're the only issue I noticed. I submitted it several years ago and was hoping for a 7. Think I could bump it up to at least a 6? It doesn't exactly fit my 6+ set-build, but it's got such great eye appeal that I find it hard to part with.
