Identical in value (5)
I believe the answer is:
equal
'identical in value' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for equal that I've seen before include "Be as good as, match" , "What Orwell's animals were" , "The same; even" , "Fifty-fifty" , "Identical, add up to" .)
