The Mauve is extremely difficult to find, most of the time copies that do surface are less than VG. Never found in any quantity to my knowledge; band members contacted did not have copies. Been trying to upgrade from a strong playing / clean VG for over 20 years.
Shyres - same deal, although not quite as difficult to find as the Mauve 45. Both 45s undervalued in the Wickham price guide, IMO.
All the other sides on Cori are not too hard to find - meaning they still surface from time to time out here in the wilds. I've had VG++ / mint minus multiple spares of all the other garage sounds - CC & Chasers, Sole Survivors, Riffs, Royals and Valkyries, and the End (on Insegrevious, but is actually a Cori label release).
