I have been thinking more about the number of Wagners out there. REA estimates roughly 50 in the latest auction write-up. That number makes sense. That means if roughly two are sold every year, that on average the average Wagner stays in its temporary home for about 25 years.
Also, since people like Rob Lifson have been following new finds since the late '60's or early '70's when there were less than 10 known, I would think he would be in a good position to make a reasonably accurate estimate.
I know some estimates are as high as 80-100, but those numbers always seemed high to me. I just think they would be seen much more frequently if the number was that high. If there were a hundred and two a year are publicly traded, then the average owner would hold their copy for 50 years! That seems very high on average.
