If you refer to the collector value of 1954 Australian coins, not much. Any value would be dependent on the condition of the coins.
According to your serial number, your pistol was made between the years 1954-1967.
I am going to refer you to Beretta Customer Service- 1-800-BERETTA, extension 2003. Between 1925 and 1954, Berettas are dated from a number/letter code stamped near the proofmark, not from the serial number. However, my references show the 950B as a .22 rimfire, not a .32 ACP.
