I have on my Internet Archive files a McElroy Chart of Codes and Signals.

Highlight of the American Morse section:

You will notice $ is SX sent as two letters in American Morse, it sounds 
like "SL" in International Morse.

So the sound of the dollar sign was never SX, but SX was what was sent 
in American Morse.  That being said, I received a telegram from 
Netherlands coast station ScheveningenRadio / PCH and RCA San Francisco 
with the operator sending very slowly "SX" for dollar sign - which isn't 
even admitted in telegrams in International service.

International Punctuation from the same chart - the only thing that has 
changed Post WWII is that left parenthesis became KN and right (ending) 
stayed the same as KK.
