Thunderbirds Collectibles?

[Losidan]

Hi,
Having sort out the other day I stumbled across these which I have had in a box for a few years. Someone gave them to me to pass on if I knew someone doing a car boot. I kept them as I thought they were too good for that...Just wondering if they have any value?
All 7" vinyl in good nick. Although I have never played them the black and white covered one is the theme tune and the other three are spoken word stories I believe.
Any ideas gents?

I would think they'd be collectable, sad but true.

yes, they were probably collectable during the initial re runs of them (that i watched as a child) in the early - mid 1990's - even more so now.
