Your question isn't nearly specific enough. The U.S. minted over a dozen different denominations and varieties of coins in 1865. There is not "the" 1865 coin; there were millions of coins minted that year. You can look at a site such as coinfacts.com for pictures. See the Related Link below.

There have been a number of strange coin denominations minted at different times, but I can find no reference to a Twopence Halfpenny coin. There was a Twopence-Farthing coin produced very briefly during the reign of Queen Elizabeth I about 1560, but this was a modification to an earlier coin.

No, such a coin was only minted in 1974 and all examples save for a few were supposed to have been melted down.
You need to provide a lot more details. The U.S. minted about a dozen different denominations in 1886 and at about a half dozen mints. Please post a new question with the coin's denomination and, if you can locate it, the mint mark.

Such a coin does not exist. The last British Halfcrown coin minted for circulation was minted in 1967. The last British Halfcrown Proof coin was minted in 1970.
The only Crown (Five Shilling) coins minted in Australia were the 1937 and 1938 Crowns which were round. The only square coins minted in Australia were copper/nickel coins of Halfpenny and Penny denominations in 1919, 1920 and 1921 as trial patterns and were never put into circulation. They all featured a kookaburra on the reverse.
