Enlarging lenses

Hi all, just wondering if anyone knows what I should be asking for if I were to put these lenses up for sale, if that is they are worth anything at all ?

Or are any of them worth hanging onto.

Schneider Kreuznach Componon 80mm 5.6
( this has a smaller mounting thread, maybe 25mm or so )

Meopta Anaret S 80mm 4.5.

Komuranon-S 75mm 5.6

I am saving for something nice and don't see the point in hanging on to too many lenses.

Thanks

Best advice I can give you is to check the completed Ebay auctions for similar items. If you plan to sell locally, then I couldn't say. That all depends on your locale.
