Hi everyone
In searching through Numista site I found the closest match to this coin, but the mint mark choices do not seem to match my coin, I don't believe it's a Bell, it's not an A and from the site below Numista I don't believe it's the Hand, weight is 1 gram,17 MM https://en.numista.com/catalogue/pieces55827.html
Firstly, based on the weight and the two pellets behind the Queen's head, I would agree that is a twopence or half-groat. The first to fourth issues had no pellets to the obverse and there was no fifth issue half-groat so that means it must be sixth issue ((1582-1600) or seventh issue (1601-02). I have updated the Numista page and double-checked my copy of Spink but still can't be sure about your mintmark, the wear is just a little bit too heavy.
Just because you can't see it ... doesn't mean it isn't there - Anon.
