Like new dollar bills (5)
I believe the answer is:
crisp
'like new dollar bills' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for crisp that I've seen before include "Potato snack" , "Hard, brittle; a snack" , "Brittle, crunchy" , "snack > firm" , "Firm and fresh or easily crumbled" .)
