Less I spent & most sold for was Herby Brown One More Broken Heart paid either 10 or 20p from a record shop in Chapel Street Market London 1980/81. It was a newish release, shop owner used to get new stuff from Moondogs & if they didn't sell he would chuck them in the bargain box. Fast forward approx 20years & it's in manships book @ £2k. Eventually agreed £1600 with a collector abroad. He sent cash in three packs of cheap crap records, 500, 500 & 590. The last one they ran out of sterling at his bank & he said he'd forward it on. I told him to buy himself a beer instead
A few weeks after I sold it Randy Mather PM'd me on here asking if i would send him an mp3 of it. He'd played Sax in the studio but had never heard the record or even the finished version, sadly I couldn't help out. Strange thing was I only bought it because I recognized the name Randy Mather
Also picked up a copy of Tom - Emmanuel And Ron Experience - When You Lose Your Groove, again for 10 or 20p in the same shop plus loads of motown but nothing rare.
As many others I'm sure you always wonder what you left through lack of knowledge
