Belinda Downie joins Ben Davis in studio at Brisbane 4BC. The topic? That a twenty dollar note, issued in 1824, is today worth half a million dollars.

Brisbane's Ben Davis was amazed and excited by the Bank of New South Wales Twenty Spanish Dollars banknote and proud of its connection to the city of Brisbane.

He was equally excited by the Uncirculated 1813 Holey Dollar that he held in his hand.
