Hope Sophie accepts money (4)

I believe the answer is:

peso

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

'money' is the definition.
(I know that peso is a type of currency)

'hope sophie accepts' is the wordplay.
'PESO' is hidden within the letters.
However, I'm uncertain how this is indicated.

Can you help me to learn more?

(Other definitions for peso that I've seen before include "Latin American money" , "Mexican monetary unit" , "Chilean currency" , "Mexican coin" , "ready for Mexican" .)

I've seen this clue in The Mirror.
