Just had a look at this and i think it is a unofficial farthing with the image if a tea canister.I have had a look in my book and the nearest i can see is one from Bilston Staffordshire issued by Beckett. That is if the 1757 is actually the ILST of Bilston under the bottom of the canister.Trouble is that would not make it very symetrical though.There are plenty of 19th c farthings that used an image of a tea canister so thats where i would begin to look for a full i.d. ......Mick
p.s if you look where the legend starts on the token it looks like it starts with "CO" which might be "coffee" which knocks out the Bilston theory..Will keep looking.Here is an image of a 19th c token of Hadduck of Birmingham
