UN at less than face

I still have a goodly number of pre-1987 UN stamps that were purchased from the
UNPA at face value in their years of issue.  I'm cutting back on my collecting
interests, and am willing to sell these at less than face value (sorry, no
Scott 38).  If you'd send me five dollars, I'll send you six dollars face value
in all different MNH UN (NY) stamps.  I'll fill your want list (as much as
possible) at face value.
