Old boy with lines in face (moneyed type) (7)
I believe the answer is:
obverse
'face moneyed type' is the definition.
'obverse' can be an answer for 'face' (thesaurus). I am unsure of the 'moneyed type' bit.
'old boy with lines' is the wordplay.
'old boy' becomes 'OB' (abbreviation for a private school 'old boy').
'with' is a charade indicator (letters next to each other).
'lines' becomes 'verse' (lines of poetry).
'ob'+'verse'='OBVERSE'
'in' is the link.
Can you help me to learn more?
(Other definitions for obverse that I've seen before include "Side of the coin containing the principal figure" , "Verbose about coin side" , "Coin's head side" , "One side of a coin" , "Heads as opposed to tails" .)
