Anyone care to take a guess regarding this coin?

[Pierre_Henri 50]

In the first picture I show an uncirculated 1941 two-shilling (a digital picture and a scan of the same coin)

 

 

In the second picture I show a proof 1947 two-shilling (a digital picture and a scan of the same coin)

 

 

In the third picture I show our mystery coin (I blanked out the exact date in both the digital picture and the scan) In my opinion it is a proof coin when compared to the uncirculated and proof coins shown above.

 

Guess what is the date of the coin?.
