'st johns' token -- Unofficial Farthing??

[will1976 231]

I realise this is a long shot with the name 'St Johns' being so common but I bought this at a local flea fair hoping it was an unofficial farthing. It's not in the catalogue as one but is the same size etc and it now has me intrigued, any suggestions welcome. Blank reverse apart from a beaded border

More likely to be a communion token

I did wonder that but all the ones I've seen are larger and of white metal

There are one or two in bronze but the lack of any other info on this one is puzzling.
