Crossword Genius

My numbers! (4)

Ross

I believe the answer is:

ones

I believe this is a double definition.

'my' is the first definition.
('one's' is a humorous equivalent to 'my')

'numbers' is the second definition.
(one is a kind of number)

(Other definitions for ones that I've seen before include "(Of ship) returning to port of origin" , "1 & 1 & 1" , "Singles" , "Individuals" , "Units" .)

I've seen this clue in The Guardian.
