Thanks royals and proceeds (7)

I believe the answer is:

takings

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

'proceeds' is the definition.
(synonyms)

'thanks royals' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'royals' becomes 'kings' (I can't justify this - if you can you should believe this answer much more).
'ta'+'kings'='TAKINGS'

'and' is the link.

Can you help me to learn more?

(Other definitions for takings that I've seen before include "What's in the till" , "gold received?" , "Income from transactions" , "Cash receipts" , "Income from sales, etc" .)

I've seen this clue in the Sydney Morning Herald.
