This PSA 5 Cy Young sold in Sept for $5k. And this SGC 5 sold on Nov 7 for $3.6k. The one that sold for $10k is nice, but not more than twice as nice, nice.
And yeah I agree that certain well-centered cards with nice registration are hard to come by, but certain cards are easier to find in these conditions than others. If you look at Worthpoint you'll find a lot of nice looking Cy Young Portrait examples.
The other top tier HOFers like Walter Johnson Portrait and Cobb Red Portrait (even though it's a superprint) I think are much tougher to find in great eye appeal condition.
And no I don't own any of these. And yes I'm jealous of those that do.
