Modest collection of two notes and a coin? (8)
I believe the answer is:
reticent
'modest' is the definition.
(thesaurus)
'collection of two notes and a coin?' is the wordplay.
I cannot really see how this works, but
'notes' could be 'ce' and 'ce' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for reticent that I've seen before include "Not forthcoming" , "Not revealing one's thoughts readily" , "Uncommunicative" , "Backward in coming forward" , "Reserved, not revealing thoughts readily" .)
