The prevailing bidder did not get a good deal for the money. As I point out on page 145, "A cache of these was found in ~2009, greatly lessening rarity." I reduced the RSIN to a "4" and chronicle the sustainable guide value at $275. Interestingly, the vast majority of this found cache has been peddled by this dealer.
