Retain bets, with no time for tokens (9)
I believe the answer is:
keepsakes
'tokens' is the definition.
('keepsake' can be a synonym of 'token')
'retain bets with no time' is the wordplay.
'retain' becomes 'keep' (keeping is a kind of retaining).
'bets' becomes 'stakes' (staking is a kind of betting).
'with no' indicates named letters should be taken away.
'time' becomes 't'.
'stakes' with 't' taken away is 'sakes'.
'keep'+'sakes'='KEEPSAKES'
'for' acts as a link.
(Other definitions for keepsakes that I've seen before include "Souvenirs" , "Relics" , "Mementoes" , "Seventeen [MEMORABILIA]" , "Mementos" .)
