How much are these lenses worth?

[kit kat]

I have a few lenses that I have inherited they are for from a 35mm Canon film camera and although they fit on my EOS 350D they sometimes come up with an error message when taking a picture. I am looking at selling them and buying some new lenses for mine. If anyone knows how much I should be asking for them I would be very appreciative.
The three lenses are:

Sigma AF TELE 400mm f/5.6 APO

Sigma 70-210mm f/4-5.6

Sigma 28-70mm f/3.5- 4.5

Thanks

If they suffer the standard sigma problem for old lenses on new bodies then not very much at all, the normal problem is they will only shoot wide open in which case the only one of these lenses with any value is the 400 and even then it won't be much.

The Sigma 70-210 works on my 40d at 210mm@f/5.6 only. No other combinations work. It's really sharp, but it's useless for anything other than sports really. Slow AF, too.

£30 if you're lucky.
