Further details
Other known specimens of this rarity include Norweb:2387; Taxay plate coin; Roper:74. As noted in Bowers and Merena's sale of the Norweb collection, Part II, the weight of this denomination is more closely aligned with the Farthing denomination current under George I, than with the Halfpenny denomination displayed on the coin.
