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.
If you refer to the collector value of 1954 Australian coins, not much. Any value would be dependent on the condition of the coins.
