Thanks for the offer Dave but I'm not selling them, just asking how I can 'very roughly' value them for the sake of my Will, which I've finally found time to write.
However, to answer your question;
60% British, 40% American imports.
Good collection of British, including a large selection of Twisted Wheel originals, all the first 100 TMGs, every black Chess, lots of Stateside, London, Liberty, Columbia, Parlophone, Vocalion, HMV, UA, CBS, etc, etc, many Demos amidst them all.
Plenty of rare R&B and a few rare Northern.
Also includes about 400 British labelled Lps from the 60s.
I don't suppose the figure for my Will needs to be that accurate. Does it?
That accuracy will come to matter if and when I ever made an insurance claim on them. Fingers crossed I never do.
I haven't got time to go through them all, 70% of them are at my Mum's house, and condition would have to be considered, although most are excellent.
Does any of this help towards a rough estimate?
