Your points are well-taken Jim. However, there are collectors who will pay, or who have paid, $50 and up for some of the few truly rare keys that are out there. Reason we don't see these keys often is because most of the time they are offered via private sale, or in trade for other scarce to rare keys. One thing is for sure ... you won't find them in any Round Robins!

I'm simply trying to determine a maximum value that some collectors might consider for a small number of very tough keys. Do any readers of this thread think that $50 is a fair number...; or higher? How about you deep pockets guys?
