I meant to post this a ways back, but just realized I hain’t as yet.
MeFi pointed out Popspike.com, a searchable archive of ebay auction resluts for rare vinyl. My own rarities, “Songs Pictures and Stories of the Fabulous Beatles,” and a VJ promo EP are apparently fetching healthy amounts. I sould temper any excitement, however, as my copies are very, very beat-up.
