Does anyone pay attention to the value of comics?

Reckon i probably have 400-500 Roy of the Rovers comics from 1979 to 1991 (not all consecutive but quite a number are).

Also have some Shoot magazines from mainly 82/83, about 80 of them.

Tiger & Eagle roughly 400 from 1979 to 1988, as above not all consecutive bit quite a number will be.

I've had a quick look on eBay but as i've not really been tracking them properly its difficult to tell their proper value.

(Its a wee bit alarming i thought i stopped buying Roy of the Rovers in my teens but it turns out got them right up until i was 21

Any help appreciated,
Cheers

as an aside any half sensible bids entertained
