Tough to say. I definitely see some English letters, but not enough to concretely ID the coin/token. I think I see a date, I attached a picture and outlined it. Almost looks like 1841 or 1847......beneath a crown (perhaps)?
EDIT: the one pictured seems to be a little different from yours. I see a "J" on the back above the 3, which I don't see in the linked photos. I assume there were various makers of these...
