1932 1/2 Pice

I can see why the question was asked, but I don't have the answer, unfortunately.
Proof coins produced in 1932, as a general rule, did not have polished fields.
It may very well be a proof restrike, or simply a specimen restrike as can be seen from the pictures.

Perhaps Mint records may shine some light to provide a definitive answer, but those records may very well prove hard to obtain, unless
Spinks in their Numismatic Bulletin, or
B.A Seaby in their Numismatic Circular, may have an article published.

Noble Numismatics in Sydney may be able to provide a better answer than me, they may have a bibliographic record to a required to a relevent published article.

The British Numismatic Association may also have a reference to a relevent published article.

Superb coin!
