Can anyone venture an opinion as to why the '40-S to '45-S Walkers in NGC MS67 are going for so much more than the '39-S Walker in the same condition?
For example, there's a '40-S Walker going for just under $8,900 on e-bay right now, and we all know how scarce a '41-S Walker is in the same grade.
By way of comparison, I've seen '39-S Walkers for sale at under $1,000...
