FWIW, I have found that accessing # on the standard British (ie. 
'International') Mac keyboard is complicated too. You have to do Alt+3. 
  And I still haven't figured out how to access it at all when using my 
Windows VM software for DreamWeaver with the UK (Apple) keyboard set 
(though I suppose it's there somewhere).

As for $, since it is widely used in PHP, Perl and regular expressions, 
I think the cat is out of the bag and the horse has bolted the stable. 
If it is necessary to prepend variables with something, then this seems 
a reasonable choice, because it will be familiar.
