Amlwch, Parys Mines Co., uniface trial of the unfinished pattern halfpenny reverse die in white‑metal
[1788], as above but on a smaller white‑metal flan with a ragged part‑filed edge (DH 272 Bis), Extremely
Fine, some residual lustre with many small letters punched in field, unique?
Ex. Spink 24 Jan 2008, and more than likely ex F S Cocayne.
As preceding lot, this is obviously a trial striking of the reverse for one of the currency issues.
