Arcade coins (6)
I believe the answer is:
tokens
'arcade coins' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tokens that I've seen before include "They serve as representations of payments or feelings" , "Symbols as of esteem - or vouchers" , "Disks as substitute for coins" , "Signs or symbols of something" , "Keepsakes or vouchers" .)
