I was thinking, how much aviation themed currency (notes or coins) is there out there. I don't mean special collectors issued notes/coins that were not in general circulation, but just currency in general circulation (including special coins or notes that are issued for general circulation).
To kick the ball rolling, the Australian $20 note features on one side Rev John Flynn, who started what became the Royal Flying Doctors Service. The note includes a picture of De Havilland DH-50 VH-UER.
More info about Flynn can be found at http://www.rba.gov.au/CurrencyNotes/people_on_notes.html#flynn
There was also a special issue $1 coin, commemorating Charles Kingsford Smith. Unfortunately, I don't have any on me, and can't recall what year it was issued.
So, open to the forum, what else can you come up with?
