Getting record collection valued

Put the album name and catalogue number into discogs.com and you will get average prices, you have to be careful to identify your version because there could be 15 or more reissues of an album and prices can differ drastically from a lot to sod all, of course it also depends on condition, stuff that skips etc is worth nothing, I have a feeling though that their albums won't fetch much as there were so many pressed. For instance near mint 77 issued Rumours on vinyl going for 3.99. Though if you had some of their early singles and eps in mint condition might be worth 30 or 40 each.
