I agree with Ross on this one as nobilis is hard to find , I haven't a clue
as to why though I would guess that it's like the yellow generalis being
that it's so common that it's unprofitable to sell.
As to the question of the two subspecies ; Conus nobilis renatae Cailliez,
1993 and Conus nobilis friedae da Motta, 1991 I don't see much mention of
either except in Da Motta's book on classification and this is not a book
for identification but more of a guide as to where the form of a particular
conus falls into.
Generally if Tom Rice doesn't list the shell in the price guide then it's
either relatively new or it's not recognized as a  separate subspecies .
They only look like slight color forms and even that's a
stretch.....ferreter
 
It seems that "normal" Conus nobilis is also a tough cusomer to find-
