Royal Mint has new coinage? It's standard state of affairs (9)
I believe the answer is:
normality
'standard state of affairs' is the definition.
(how things are normally)
'royal mint has new coinage?' is the wordplay.
'has new coinage?' is an anagram indicator.
'royal'+'mint'='royalmint'
'royalmint' is an anagram of 'NORMALITY'.
'it's' is the link.
(Other definitions for normality that I've seen before include "to be expected" , "conformism" .)
