Coins newly minted using sound waves (5)
I believe the answer is:
sonic
'sound waves' is the definition.
'sonic' can be an answer for 'waves' (I've seen this before). I'm not sure about the 'sound' bit.
'coins newly minted' is the wordplay.
'newly minted' indicates anagramming the letters (mint can mean to forge or create in a factory).
'coins' anagrammed gives 'SONIC'.
'using' is the link.
Can you help me to learn more?
(Other definitions for sonic that I've seen before include "Boom of jet aircraft" , "Employing sound" , "Involving sound waves, say a boom" , "Using waves" , "Producing sound" .)
