Hardly worth mentioning (7)

I think it could be either:

trivial

nominal

'hardly worth mentioning' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for nominal that I've seen before include "Ironical understatement (gram mar.)" , "Trivial" , "In name only or of token value (7)" , "In name or form only" , "Minor" .)

I've seen this clue in The New York Times.
