One timid deletion could become a collector's item (7,7)

Ross

I believe the answer is:

limited edition

'a collector's item' is the definition.
(eg a limited edition book might be a collector's i)

'one timid deletion could become' is the wordplay.
'one' becomes 'i' (Roman numeral).
'could become' is an anagram indicator.
'i'+'timid'+'deletion'='itimiddeletion'
'itimiddeletion' anagrammed gives 'LIMITED EDITION'.

(Other definitions for limited edition that I've seen before include "Rare book" , "Small number of copies" , "An issue of a fixed number" .)

I've seen this clue in The Independent.
