Memory lane auction results last night

[Fred]

How many Henderson RC 9's and 10's are there? Was the "10" sold in Memory Lane the same as the card that sold for $181K? If so, that's a dump of about 25%. If it were a $1K card, 25% is minimal, but when looking at a 6 figure card that's a chunk of change.

For clarification, how much would a mid-grade 1933 Goudey set sell for? What about a low-mid grade T206 set (sans the big 4).

I hear these stories and just cannot understand the rational for paying up for a frigging number on a flip. It'd be interesting to compare the 9's and 10's side by side and say, hey, there's over $100K difference in those cards. It's frigging cardboard that's not even 50 years old.
