The 1933 proof or specimen shilling was produced as a representation piece by the Royal mint Melbourne after the production run was complete by pairing an obverse working die with a used reverse working die . Both dies were polished before production to produce mirror fields on the end product, but they are certainly not up to the standards of typical Melbourne mint proof strikes. Consequently the coin can be characterized by a worn reverse strike particularly pronounced on the star, top of shield and emu, similar to the 1933 specimen florin.
