Head seen on pound, English coin (5)
I believe the answer is:
noble
'coin' is the definition.
(I've seen this before)
'head seen on pound english' is the wordplay.
'head' becomes 'nob' (I've seen this in other clues).
'seen on' says to put letters next to each other.
'pound' becomes 'l'.
'english' becomes 'E' (abbreviation).
'nob'+'l'+'e'='NOBLE'
(Other definitions for noble that I've seen before include "Of high rank or birth" , "Maybe count" , "Former gold coin" , "Illustrious, peer" , "Lord" .)
