50 Pounds

The Bank of Adelaide was a modest South Australian institution that never achieved the national reach of the larger trading banks, and its high-denomination notes were issued in strictly limited quantities — primarily for interbank transfers and commercial settlements rather than retail circulation. A 50-pound note in everyday hands would have been extraordinary; this was serious commercial paper.

The bank was absorbed by the Union Bank of Australia in 1910, which makes this issue a terminal one. Notes outstanding at the time of amalgamation were either redeemed or cancelled, and very few survived outside bank records.
