Stupid European coin (4)

I believe the answer is:

dime

'coin' is the definition.
(dime is a kind of coin)

'stupid european' is the wordplay.
'stupid' becomes 'dim' (similar in meaning).
'european' becomes 'E' (abbreviation e.g. EU).
'dim'+'e'='DIME'

(Other definitions for dime that I've seen before include "US ten cent piece" , "Ten cents piece" , "US ten-cent coin" , "US coin, one-tenth of a dollar" , "US 10 cent coin" .)

I've seen this clue in The Mirror.
