what do you do when you have too many great lenses

I have a 70-200vr and nikon TC 14 and 17.  But before i got the 70-200 I also got very good used 80-200 push pull and 180d 2.8

all are very sharp wide open

I still use the 70-200vr for sports and still use the 180d randomly for portraits or other shots since its small and makes it in the bag.

But the 80-200 just does not get used.  Its near mint condition with very nice leather hard case.  very sharp, even wide open.  Problem is i bet i barely get $400 if i sell it, so i have not.

just curious if you have any glass you cant part with, even if you dont use it much

maybe i can save it with my d200 for the kids if they ever get into photography
