So, I've gone through my Characters listing and Realm listing and deleted a few more toons who were sitting unused on some realm I had toyed around with...
On one PvP realm I had set up on since my nephews once played there, I had a level 10 warlock and a level 1 bank toon and already had 50g saved up from the bit of Auction House work I had done while levelling that far.
I hate money being deleted outright, so I logged into my toons before deleting them, and did a /who to see was in my zone.
There was one other player in my zone - lucky winner!
I mailed them the 5g and few silver I had on my level 10 and explained in my letter that I was about to delete my characters on that realm because my main ones were over on Zul'jin but that I didn't want the cash to go to waste. I then mentioned I'd also log into my bank toon and send them some more money from there.
I logged into my bank toon and found I had 56g :) I sent pretty much all of it, plus a few low level cooking recipes I had on me that this level 10 mage might be able to use. Again, I attached a letter with it to explain where the cash was coming from and why I was randomly sending it their way.
I hope I hit someone new to the game and not someone to whom 60g isn't a big donation :)
