Mark, first of all, thanks for the kind words re my book.
If the cards aren't out there at all other than the ones on eBay, then the ones on eBay aren't priced at a premium. Truth is, given the small supply of these cards we really don't know what the 'right' price is at any given time. To quote an eminent scholar (me): "A total lack of transactions speaks volumes as to how many cards are really out there above the radar. If I report a card as not transacting for years and one shows up, you want to know that you need to jump on that specimen if you want to own one, not that the ‘book’ on the card says it is worth X..."
It sure is a great set, though
Full disclosure: I have no financial interest in any of the cards on eBay. The N269s I have are not for sale.
Brent, I haven't seen the previews on the LOTG Ringside sale yet but if there are any I will post it here first.
