Good fleece for spinners and other handcrafters has a value, yes.
Here's an example.
Someone on Ravelry was destashing some fleece; she just wanted postal costs, needed to make some space and wanted to know her collection was going to be put to some use.
I bought a scoured (washed) Shetland, cost me £3.40 for the postage plus the PayPal charge, so about £3.65 or thereabouts.
The fleece is pretty colours, beautifully crimped, well washed - but brittle as heck and completely useless. (Except to demonstrate brittle fleece to spinners - I'll have a sample with me at the Festival for exactly that reason.

)
So I can get useless fleece for £3.65/each. (Yes I'm sure she'd refund the postage - but it was clearly a mistake through ignorance and she hadn't profited by it, so I spared her blushes.)
Or I could buy fleeces off eBay for £5/each plus postage - and find them also not good for spinning. Or I could pay a friend a tenner for a fleece I can use.

Bargain!
Price, cost and value.
Fleeces at Woolfest were priced mostly in the £10 - £20 bracket. I was very tempted by a £20 Portland - beautiful condition, lovely fawn colour, gorgeous soft fleece. But didn't as we were en route on holiday and I thought it a bit antisocial to carry an unwashed fleece all round Wiltshire and Devon with us!
