Al gives dad a new coin (6)
I believe the answer is:
pacino
'al' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'dad a new coin' is the wordplay.
'dad' becomes 'pa' (both can mean one's father).
'a new' indicates an anagram.
'coin' anagrammed gives 'cino'.
'pa'+'cino'='PACINO'
'gives' is the link.
Can you help me to learn more?
(Other definitions for pacino that I've seen before include "Al --, actor" , "Hollywood star" .)
