Note fine Buckinghamshire village (5)

I believe the answer is:

fiver

I'm a little stuck... Click here to teach me more about this clue!

'note' is the definition.
(I know that fiver is a type of note)

'fine buckinghamshire village' is the wordplay.
'fine' becomes 'f' (abbreviation).
'buckinghamshire village' becomes 'iver' (I can't justify this - if you can you should believe this answer much more).
'f'+'iver'='FIVER'

Can you help me to learn more?

(Other definitions for fiver that I've seen before include "Note worth 500p" , "Where to see portrait of Elizabeth Fry" , "Smallest English note" , "paper ready" , "money" .)

I've seen this clue in The Independent.
