Yes, the 1939 coin is worth more, but only in Mint Uncirculated condition, otherwise they are worth about the same.

There is no documented evidence of a 1942 Threepence with a blank reverse, but any genuine minting defect or irregularity would increase the value of the coin. A British 1942 Threepence (was only minted for Colonial use), uncirculated and in absolute mint condition could fetch up to £40 GBP. If it has been circulated but still in good condition, it might fetch up to £5 to £15 GBP. A British 1942 Threepence (dodecagonal - nickel brass), uncirculated and in absolute mint condition could fetch up to £7 GBP. If it has been circulated but still in good condition, it might fetch up to £2 GBP. A reputable coin dealer will be able to give a more accurate valuation.
The rarest general circulation Australian Threepence, as distinct from the most valuable, would be the 1942 Threepence minted in Melbourne of which there were 520,000 minted. The other Threepences minted in 1942 were minted in the San Francisco (mintmark = S) and Denver (mintmark = D) mints in the USA. Threepences from this period that were struck in Melbourne have no mint mark. All others will have a mint mark on the reverse below the fourth digit of the year indicating the city where minting occured.
