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.
Any collector value would depend on the country of origin and the condition of the coin.
Such a coin does not exist. All Australian Threepences from 1910 to 1944 inclusive were made from sterling silver.
The small 50% silver Threepences (16mm) were still being minted for the Colonies from 1942 to 1945 inclusive. The changeover to the 12 sided nickel-brass Threepence (21mm) commenced gradually from 1937.
Yes, the 1939 coin is worth more, but only in Mint Uncirculated condition, otherwise they are worth about the same. The 1942 "One Dot" Threepence is a minting error and represents about 8% of the 1942 Threepences minted.
Such a coin does not exist. Threepences have never been made from copper.

All Australian Pennies minted from 1938 to 1964 inclusive feature a kangaroo on the reverse. The only Australian Coins to feature wheat was the 1938 to 1964 inclusive, silver Threepence coins.
In Great Britain, the last Threepence coin produced for circulation was minted in 1967. A proof-only Threepence coin was also produced in 1970. Finally, small numbers (usually about 2,000 to 4,000 each year) of silver Threepence coins are produced annually (as they have been for several hundred years) as part of four-coin Maundy sets. The Threepence was initially to be withdrawn and demonetised on the introduction of decimal currency in 1971, but they remained legal tender until about 1974 or 75.
