Collector of rings and fancy coins (5)
I believe the answer is:
sonic
'collector of rings and' is the definition.
I can't tell whether this defines the answer.
'fancy coins' is the wordplay.
'fancy' indicates an anagram.
'coins' is an anagram of 'SONIC'.
Can you help me to learn more?
(Other definitions for sonic that I've seen before include "Relating to sound waves" , "Like mine, possibly" , "Kind of boom" , "Sort of boom" , "Relating to the speed of sound" .)
