Bll1008 - Unprinted Label/emi Acetate

Hi,

First post so go easy! I've been going through my Uncle's old collection and there's a few that I thought might be of interest.

Bell - BLL1008 - James & Bobby Purify - I Can Remember. Unprinted label on the A Side.

Colpix - PX11022 - Ron Winters - Snow Girl - Promo

EMI - Acetate - The Contours - Baby Hit & Run

Anyone got an idea what they'd be worth?

Thanks in advance,

Tim
