Sterling Silver?

A couple of months ago we wrote a brief note about a copy of Horace Silver’s Song For My Father selling for $334. The note started a discussion about changes in the jazz collectibles market wrought by eBay. Well, yesterday we were watching another copy of Song For My Father because we noticed that the bidding had gone over $150. The record eventually sold for $198. Not outrageous, but still pretty high. The one that surprised us this time came from the same seller. It was a copy of Silver’s Blowin’ the Blues Away. This one sold for $229.50 — bit it was a Stereo pressing, not a mono. Is there any explanation for this? If you have one, please send us a note or comment on the site.
