Token, sign (6)
I believe the answer is:
symbol
This clue is a double definition.
'token' is the first definition.
(I've seen this in another clue)
'sign' is the second definition.
(I know that symbol is a type of sign)
(Other definitions for symbol that I've seen before include "Something representative" , "Emblem, icon" , "Sign that represents something else" , "Something that stands for something else" , "Material object representing something abstract" .)
