Both a popular and rare release, only 20,201 of these three-coin sets - 2 x 20c coins and 1 x 50c coin in decorative cards - were minted to commemorate the 70th anniversary of the bombing of Darwin in 1942. These are beautifully presented and packaged, and all are in perfect condition. Renninks values these combined at $150. Surplus to a private collection, this special set deserves a good home with a collector that will preserve them.
