This is just an addition to the Proof/specimen topic: See Lot 910 (hope I remembered the number). Many times there are coins that can fool, and I believe this "proof" 1891 shilling is an example. It appears to be early die state of a CURRENCY piece to me, complete with prooflike fields and nice micro-pebbly appearance of Vick's bust device. Many coins from the Victoria period, spanning all the way back to first issue demonstrate this, and my opinion most common in the 6d and shilling denominations.
