Rare mono?
There’s a lot less of it around these days, to be sure.
Case in point: Well-known record dealer John Tefteller has three copies of Meet the Supremes (Motown 606) in his September auction, all three mint, all three still sealed. The minimum bid he’ll take on the mono version is $250; on the stereo, $200.
Both of those have the 1965 reissue cover, which you can see here. The original “stool” cover from late 1962, which shows the girls perched on barstools, used for mono copies only — there was no stereo mix until ‘65 — pushes the price up to $1000.
(Incidentally, I used to follow Tefteller’s auctions in Discoveries, which is being folded into Goldmine starting next month; Tefteller says he’ll stick to the Web from here on out.)
(Update: My Goldmine subscription has started, in lieu of Discoveries, and Tefteller is back into the fold.)
