Hi Malkin
I'm making a very big assumption here, but I am guessing that they are part of some sort of a promotion that was run by the Apollo Cinema. The only thing I can't work out is that you say your father gave it you in the 50's and farthings were still legal tender until 1961. The Apollo itself closed in 1960 before they stopped being legal tender. It would be very unusual for any organisation to alter any coin of the realm was still legal tender in this way unless the farthing is not permanently fixed in the aluminium surround.
As for your question, I have certainly never seen one of these before, though I have seen many coins that have been formed into items of jewellery.
