That is too much information to be listed here. It would depend on whether you refer to Mint Uncirculated sets, Proof sets, or precious metal sets and which variant of any of those sets including the means of presentation and or packaging.
Such a coin does not exist. The first and only round Australian 50 cent coin issued for circulation was issued in 1966. There was a round commemorative Proof coin issued in 2006, but not for circulation.
Some years had more than one Proof set issued. If the coins are Proof sets produced by the Royal Australian Mint, an average for each year set might work out to about $60 each. A reputable coin dealer will be able to assess your collection and give a valuation on examination. It should be noted that any Mint Uncirculated or Proof coin set should be in the original packaging and condition.
