This piece is hard to put an accurate date on it as the hallmarks are very worn. I think the best indication is the outline of the Crowned Leopards Head, making it London made. Ok so we’ve narrowed the date to between 1720 - 1821. It's a very broad head. There is only half a date hallmark visible but the outline surrounding the letter is very similar in style to that used between 1740 - 1755. The rim measures 53mm in diameter x 31mm high & weighs 38.3 grams. It possibly had a liner at some stage, put it is missing, otherwise apart from needing a polish it's in good condition.
