Man with a French coin and one shilling (7)
I believe the answer is:
francis
'man' is the definition.
(I've seen this before)
'french coin and one shilling' is the wordplay.
'french coin' becomes 'franc' (I've seen this before).
'and' means one lot of letters go next to another.
'one' becomes 'i' (Roman numeral).
'shilling' becomes 's' (abbreviation e.g. Lsd - pounds, shillings, pence).
'franc'+'i'+'s'='FRANCIS'
'with a' acts as a link.
(Other definitions for francis that I've seen before include "English philosopher, d. 1626 -- Dublin-born painter, d. 1992" , "Patron saint of animals" , "Assisi saint" , "Man" , "Pope" .)
